Dujiangyan historical earthquake situation

1. The damage to Dujiangyan due to the Wenchuan earthquake will be handed in tomorrow

The Dujiangyan water conservancy project is intact, but the Erwang Temple and the Qingcheng Mountain Taoist Temple were damaged. They were officially included in the "World Heritage" at the end of 2000. "Qingcheng Mountain and Dujiangyan" are located in the center of the earthquake. Can the 2,000-year-old water conservancy project withstand violent underground shaking? Relevant staff from the Sichuan Provincial Cultural Relics Bureau said in an interview with a reporter from the Morning Post that although aftershocks continued in the area, there were no signs of damage to the water conservancy project in the Minjiang River. At present, there are only reports that the gate of the scenic spot has been slightly damaged. The Dujiangyan Water Conservancy Project is located in On the main stream of the Minjiang River at the foothills of Qingcheng Mountain, it was completed in the middle of the 3rd century BC by Li Bing, the prefect of Shu County. It was built according to the trend of nature and has three main parts: a water dike, a water diversion and a flood discharge embankment. The people vividly call it The three facilities are Yuzui, Baopingkou, and Feishayan. In an interview with a reporter from the Morning Post, staff from the Sichuan Cultural Relics Bureau said that due to the interruption of local communications in Dujiangyan after the earthquake, they were trying every means to understand the damage to cultural relics. The known news is that these facilities in the Minjiang River are basically safe at present. Although aftershocks have continued in recent days, because their designs are quite earthquake-proof, I believe that these important facilities such as Yuzui, Baopingkou and Feishayan It should be no big deal. This is why Dujiangyan can still play a role in flood control and irrigation today after more than 2,000 years. The Erwang Temple, located on the hillside on the right bank of the Minjiang River outside the west gate of Dujiangyan City, is the largest temple in China commemorating Li Bing and his son. , has been rebuilt many times in history. According to a Dujiangyan citizen, the Erwang Temple has collapsed and almost no longer exists. Qingcheng Mountain, located 15 kilometers southwest of Dujiangyan City, is a Taoist resort. There are about a hundred large and small Taoist temples scattered on the mountain. Currently, cultural relics The department received news that several Taoist temples collapsed, and some large Taoist temples also showed signs of damage such as wall cracks. The water conservancy project in the Minjiang River showed no signs of damage. The current death toll has increased to 50 Remaining people. Collapsed bungalows and high-rise buildings can be seen everywhere, and broken glass is everywhere. Touching stories: After the disaster, he bought umbrellas and gave them to students. During the May 12 earthquake, the newly renovated house of Liu Xi and Liao Chongkai, members of the Dujiangyan branch of the Peasants and Workers Party, was destroyed. After losing all their property and surviving the disaster, they ignored their inner pain. Their first thought was to do their best to help other victims. As a doctor, Liu Xi immediately joined the medical team to treat the wounded. Liao Chongkai saw the heavy rain Many victims did not have rain gear, so they immediately searched for all their belongings and bought 30 umbrellas to give to the students of the disaster-stricken school, but they themselves were caught in the heavy rain. The self-run hospital was destroyed, and the injured were rescued for free in the ruins. Members of the Dujiangyan branch of the Peasants and Workers Party, Dujiangyan bones Part of the hospital building of Zhou Xingkai, director of the Trauma Specialist Hospital (privately owned), collapsed, and a young attending physician who was treating patients died. When President Zhou Xing suffered heavy losses in his hospital, the first thing he thought of was not how to recover the losses, but how to recover the losses. All the remaining medicines in the hospital were used to treat the earthquake victims for free. Entrepreneurs donated medicines regardless of losses after the collapse of their pharmaceutical factory. Liao Qiwu, a member of the Chengdu Municipal Party Committee branch of the Peasants and Workers Party in the disaster-stricken areas, chairman of Chengdu Meikang Medical Investment Consulting Management Company and member of the CPPCC, is located in Mianzhu The pharmaceutical factory collapsed in the earthquake, and the number of employee casualties is unknown. Despite the heavy losses of the company, Liao Qiwu still donated the remaining medicines worth 89,650 yuan collected with all his strength to the Dujiangyan disaster area. All 9 ambulances of his company in Chengdu are now going to Dujiangyan Volunteer to treat the injured. When the municipal committee staff expressed their gratitude to him, he said: "It is the greatest luck that all of us are alive now. It is our duty to do our best to do something for the disaster area." 2. The earthquake damage of "Dujiangyan"

The damage of Dujiangyan in the Wenchuan earthquake

At the critical moment of Sichuan earthquake relief, the Department of Architecture of the School of Architecture and Urban Planning of our school Professors and graduate students participated in the Sichuan rescue team. One of their main tasks was to conduct on-site inspections of the Dujiangyan Water Conservancy Project and its related monuments, a world cultural heritage. Over the past few days, they braved the risk of constant aftershocks and visited the disaster sites in the Dujiangyan Historical and Cultural District one by one. After careful observation and analysis, the widely circulated rumors about the devastating damage to the Dujiangyan Scenic Area were revised and summarized in sixteen words: the whole remains, but the rafters and tiles are exposed; the part collapsed, leaving the truth behind and destroying the lies.

Dujiangyan, which was built during the Warring States Period, withstood the test of this major earthquake. The weir body was basically well preserved, except for the cracks in the fish mouth. The local area has been grouting and reinforced; commemorating the second anniversary of Li Bing and his son. The damage to the Wang Temple such as ground cracking, slope protection, and stepping stones was relatively serious. However, among the 22 individual buildings, only two, the theater building and the ancestral hall, completely collapsed, and 6 were seriously damaged. The remaining 14 were only partially damaged and generally well preserved. . Among them, the two Qing Dynasty main halls dedicated to Li Bing and his father and rebuilt during the Republic of China are intact, which is a blessing among misfortunes. In addition, the historical landscape Fulongguan in Lidui Park and the Anlan Bridge across the Minjiang River were not seriously damaged. West Street, which reflects the local customs and culture, has basically maintained its original appearance except for a few low-quality buildings built in recent years that have collapsed. The buildings on the front mountain of Qingcheng Mountain were partially damaged, but the overall structure was basically preserved.

The historical and cultural heritage of Dujiangyan can "survive the catastrophe" because of the wisdom of our ancestors. In the face of earthquakes, ancient Chinese buildings were able to "fall down walls and roofs without collapsing" because of the flexible connection method of mortise and tenon joints. In the southwest, most of them are pierced structures, with multiple trusses connecting the columns. Excellent earthquake resistance. This is reflected in this earthquake. Most of the old buildings that actually used this method did not collapse. They were only partially damaged, such as tiles falling off, wooden rafters exposed, local cracks, maintenance bodies falling over, etc. Most of the collapse was due to the design or construction quality. "Fake antiques" that are not expensive. But this does not mean that "fake antiques" will definitely collapse. The "fake antiques" made in recent decades are not necessarily "inferior". The key is whether they have ancient or modern earthquake resistance. The main reason for the collapse of "fake antiques" is that they lack the structural quality that modern buildings should have, and they do not retain the original earthquake resistance of traditional buildings. This also shows that simple modern methods are far less resistant to earthquake disasters than mature traditional methods.

It is precisely based on this understanding that post-disaster repairs should respect history, take into account the current situation, make the best of the situation, and treat both the symptoms and root causes. The essence is that we can't just "renovate the old as before" on the surface, but also correct the simple modern methods of imitating the past. We must draw on the wisdom of traditional architecture from the basic principles and restore the original appearance of cultural heritage through rectification.

Currently, the work of drafting a post-disaster protection plan for Dujiangyan cultural heritage is underway to lay a solid foundation for the next step of repair plans.

Fenglin compared the photos of Dujiangyan before and after the earthquake. He also introduced the inspection by school experts to his friends to let them know the extent of damage and the possibility of repair of Dujiangyan, a world cultural heritage, to enhance their understanding of the situation. Our confidence, courage and a little relief. 3. What impact did the Sichuan earthquake have on the historical site Dujiangyan?

First of all, it should be explained that the modern Dujiangyan is no longer the Dujiangyan built more than 2,000 years ago.

Although the Dujiangyan Irrigation System built by Li Bing and his son was a remarkable project at the time, if viewed objectively from today's perspective, it is nothing more than a sluice gate and water diversion system made of stones and bamboo baskets. channel. Due to the backward construction materials, the maintenance of Dujiangyan is very important. It must be carried out every year and overhauled every few years.

Even so, Dujiangyan could not escape the fate of being washed away and collapsed by floods many times. However, since the essence of the Dujiangyan Project is just a channel for water diversion, with a simple structure, it can be easily repaired after water damage. Therefore, after the collapse, the impact will be small and it can be repaired quickly.

It was not until the 1970s, when we used modern concrete materials to completely repair and transform Dujiangyan, that Dujiangyan completely got rid of the fate of being damaged and repaired every year, and truly became a modern construction site. water conservancy projects. "According to People's Daily News on May 14, although the earthquake caused cracks in the fish mouth of the Dujiangyan Water Conservancy Project and the collapse of the Waijiang Gate management room and the backup generator room, it has not yet affected the safe operation of the project." This is enough to show that Dujiangyan and Like many modern projects, it is impossible not to be affected and damaged by earthquakes.

It’s just that Dujiangyan’s function and structure are simple, and its safety requirements are not high. Therefore, its safe operation will certainly not be affected after damage.

4. How was the damage to Dujiangyan caused by the Wenchuan earthquake

The Dujiangyan water conservancy project was intact, but the Erwang Temple and Qingcheng Mountain Taoist Temple were damaged

Qingcheng Mountain and Qingcheng Mountain were officially included in the World Heritage List at the end of 2000 Dujiangyan is located in the center of the earthquake. Can the 2000-year-old water conservancy project withstand violent underground shaking?

The known news is that these facilities in the Minjiang River are currently It is basically fine. Although there have been constant aftershocks in recent days, because its design is quite shockproof, I believe that important facilities such as Yuzui, Baopingkou and Feishayan will not be seriously affected. This is also the reason why Dujiangyan can still play a role in flood control and irrigation today after more than 2,000 years.

The Erwang Temple, located on the hillside on the right bank of the Minjiang River outside the west gate of Dujiangyan City, is the largest temple in China commemorating Li Bing and his son.

When the municipal committee staff expressed their gratitude to him, he said: "We are all lucky to be alive now. It is our duty to try our best to do something for the disaster area." 5. The Dujiangyan Water Conservancy Project built by Li Bing in ancient times is in How was the situation during the earthquake?

The Dujiangyan Water Conservancy Project experienced almost nothing during earthquakes over the past 2,000 years.

The World Heritage Dujiangyan Water Conservancy Project was built according to natural water conditions. After more than 2,000 years, it still withstands 7.

An earthquake of magnitude 8 must be said to be a miracle. Qingcheng Mountain and Dujiangyan, which were officially included in the World Heritage List at the end of 2000, are located in the center of the earthquake. Can water conservancy projects that have experienced 2000 years withstand violent underground vibrations? Woolen cloth? Relevant staff from the Sichuan Provincial Cultural Relics Bureau said in an interview with a reporter from the Morning Post that although local aftershocks continued, there were no signs of damage to the water conservancy project in the Minjiang River. Currently, there are only reports of minor damage to the gate of the scenic spot.
