2. Introduction to the Leaning Tower of Pisa

The title should be an introduction to the Leaning Tower of Pisa?

The Leaning Tower of Pisa was built in August 1173. It is the independent bell tower of the Cathedral of Pisa, Italy, located in the Piazza dei Miracoli in the north of Pisa, Tuscany, Italy.

The Leaning Tower of Pisa has attracted people's attention since it was built in 1173 because of its tilt and beauty. During the construction process, initially special construction equipment was used to try to stop the tilt from continuing, then columns and other damaged parts were replaced, and materials were inserted between the foundations. This greatly reduced the tilt, ensuring that the tower would last longer without collapse.

Leaning Tower of Pisa

The Leaning Tower of Pisa is one of the most beautiful bell towers in Italy.

It's not just beautiful, it's strange - it's just one-sided.

Today, it is known as the Leaning Tower of Pisa

The tower was built in 1173.

It took nearly 200 years to complete.

In 1178, when we reached the third floor, it started to tilt.

3. Travel Notes on the Leaning Tower of Pisa

Built in August 1173, it is an independent bell tower of the Pisa Cathedral in Italy. It is located in the Piazza dei Miracoli in the north of Pisa, Tuscany, Italy.

There are a group of religious buildings dotted on the lawn of the Square of Miracles. They are the Cathedral (built in 1063-13th century), the Baptistery (built in 1153-14th century), the bell tower (Leaning Tower of Pisa) and the cemetery (built in 1174). Their exterior walls are all made of milky white marble, which are relatively independent but form a unified Roman architectural style. The Leaning Tower of Pisa is located behind Pisa Cathedral.

The Leaning Tower of Pisa is 58.36 meters high from the foundation to the top of the tower, and 55 meters high from the ground to the top of the tower. The wall of the above-ground bell tower is 4.09 meters wide, and the top of the tower is 2.48 meters wide. The total weight is about 14,453 tons, and the center of gravity is 22.6 meters higher than the foundation. The circular foundation area is 285 square meters, and the average ground pressure is 497 kPa. The inclination angle is 3.99 degrees, 2.5 meters away from the outer edge of the foundation, and the top floor protrudes 4.5 meters. Tilt was first discovered in 1744.

To prove this point, legend has it that 25-year-old Galileo arrived at the Leaning Tower of Pisa one day in 1589 with his debate opponents and many others. Galileo climbed to the top of the tower and dropped a 100-pound and a 1-pound iron ball at the same time. In full view of everyone, the two iron balls landed almost parallel to each other. Later, Galileo proved through a large number of experiments that the time when an object falls has nothing to do with its mass. This is the law of free fall.

Font The tilt of the bell tower has attracted curious tourists, artists and scholars for centuries, making the Leaning Tower of Pisa famous around the world.

Experts have been debating why the Leaning Tower of Pisa tilts. Especially in the 14th century, people hovered between two debates: whether the Leaning Tower of Pisa was the result of the cumulative effect of ground subsidence that could not be predicted and avoided during the construction process, or whether it was intentional by the architect.

In the 20th century, as the survey of the Leaning Tower of Pisa became more and more accurate, various advanced equipment conducted in-depth surveys of the foundation soil, and the study of historical archives, some facts gradually emerged: The Leaning Tower of Pisa was originally designed in the original design. It was supposed to be a vertical building, but it began to deviate from its correct position early in its construction.

The Leaning Tower of Pisa tilts because of the special soil layer beneath its foundation. Under the Leaning Tower of Pisa, there are several layers of soil of different materials. Various soft silt deposits alternate with very soft clay, and the underground water layer is about one meter deep. This conclusion was reached after observing the composition of the foundation soil layer. The latest excavations show that the bell tower was built on the edge of the ancient coast, so the soil had sanded and sunk when it was built.

Vertical section of the Leaning Tower of Pisa. According to existing written records, the Leaning Tower of Pisa has been slowly tilting for centuries, and it has actually reached a certain degree of balance with the soil beneath its foundation. At the end of the third floor of the first phase of construction, the bell tower tilted approximately 1/4 to the north. In the second stage, due to excessive correction, the tilt to the south was about 0.6 when the seventh floor was built in 1278, and increased to 1.6 when the top bell house was built in 1360. In 1817, two British scholars, Cressey and Taylor, measured the tilt with a plumb line. Degree, the result at that time was 5. There is a gap of 267 years between Giorgio Vasari and him. S's survey in 1550 and Crécy and Taylor's survey in 1817 showed an increase in slope of only 5 cm. Therefore, no special maintenance was carried out on the leaning tower.

However, a project in 1838 caused the Leaning Tower of Pisa to suddenly accelerate, and emergency repair measures had to be taken. At the time, architect Alessandrodella Gherardesca was excavating around the leaning tower's originally sealed foundations to explore the shape of the foundations and reveal whether the cylindrical plinths and foundation steps were as expected. This behavior caused the leaning tower to lose its original balance, the foundation began to crack, and the most serious thing was the influx of groundwater. Subsequent surveys from this project showed that the tilt had increased by 20 centimeters, compared with a total tilt of only 5 centimeters in the previous 267 years.

After the completion of the project in 1838, the accelerated tilt of the Leaning Tower of Pisa continued for several years, and then leveled off, reducing the tilt to about 1 millimeter per year. The tower has now deviated from its natural posture by more than 5 meters.

5. One day I went to visit the famous Leaning Tower of Pisa

The internationally recognized seven wonders of the world (in order of construction time): based on the Pyramid of Khufu, the Hanging Gardens, the Temple of Artemis, Statue of Olympian Zeus, Mausoleum of Mausolaris, Colossus of Apollo in Rhodes and Lighthouse of Alexandria.

There is no conclusion in the world about the eighth wonder. In A.D.

Current Location The Leaning Tower of Pisa was originally built as a free-standing bell tower for the Cathedral of Pisa, Italy. Now because of its tilt, it has become a local landmark and a famous tourist attraction in Italy. It has also been used as a site for scientific experiments and as a site for free-fall experiments.

The Leaning Tower of Pisa was built in August 1173. It was built by the famous architect Nano Pisano. It is located behind the Romanesque cathedral on the right and is the symbol of Pisa.

The original height of the tower was designed to be about 60 meters, but after five or six years of construction, the tower began to tilt from the third floor and continued to tilt until completion. Before closing, the top of the tower had tilted 3.5 meters southward (that is, the top of the tower deviated from the vertical line). In 1990, the Italian government closed it and began renovation work.

Leaning Tower of Pisa

Time: About 1173-1370< /p>

Location: Italy

Basic information about Pisa

Height from foundation to bell tower: 58.4 meters

Foundation diameter: 19.6 meters

The tower tilts to the south: 5.5 degrees

Stabilizing the leaning tower is a very delicate project, like a doctor treating a frail old man. Although he can auscultate patients. He knew patients had worrisome reactions to each drug. Christopher, 1987

Imagine a tower built on a soft material like sponge rubber, slowly and inexorably tilting toward the edge of collapse. In addition, the masonry structure of the tower is also very fragile. As the inclination becomes larger and larger, the stress generated has approached the strength of the masonry, and there is a possibility of collapse at any time. Grouting or reinforcing the foundation on the sloping side may cause the tower to overturn. But if supported or pulled by cables, the masonry may collapse.

This passage accurately depicts the precarious situation of the Tower of Peseset. How to hide the leaning tower became the biggest challenge of civil engineering.

However, the Tower of Peseset is not only a mysterious attraction, but also an architectural treasure. Even if it is not tilted, it is considered the most important architectural achievement in medieval Europe. The tower is located in the main church square and is one of the complex buildings consisting of four dazzling white large buildings including the cathedral (main church), bell tower (leaning tower), baptistery, and cemetery. The purpose of building the bell tower is the same as other buildings in the square. It represents the pride and glory of Pisa, a wealthy city-state, so it is particularly beautiful, unique and mysterious.

Construction details

The eight-story tower is 58.4 meters tall and weighs 14,500 tonnes.

The masonry foundation has a diameter of 19.6 meters and a depth of 5.5 meters below ground level. The foundation tilts 5.5 degrees to the south horizontal line, so the seventh floor of the clock tower protrudes 4.5 meters more than the first floor.

The tower is built around a hollow column. The inner and outer surfaces of the columns were tightly covered with marble, but there were only plaster and stone between the two walls, so there were many gaps. A spiral staircase winds around the inside of the bell tower.

There are three different layers of soil under the tower. The A layer is about 10 meters thick and is a soft and deformable silt sediment that was deposited in shallow water for less than 10,000 years. Layer B is a very soft and volatile sea mud layer that has been deposited for 30,000 years and can reach 40 meters underground. The C horizon is compact, sandy soil that extends into the deepest parts of the earth.

The groundwater level in layer A is between one and two meters underground. According to the results of many soil drills around the tower, even under the bell tower, the surface of the B floor has been pressed into a disc shape by the weight of the bell tower. It can be inferred that the bell tower has sunk 2.5 to 3 meters on average, which shows how compressible the soil at the bottom of the tower is.

Architectural History

The tower was started in August 1173 under the supervision of Bernardo Pisano. But around 1178, when the fourth floor reached a quarter, it suddenly stopped. The reason for the closure is unknown, but if it had not been stopped in time, the strength of the soil in layer B would not have been able to withstand the load and the bell tower would have collapsed.

:7. The famous scenic spot Leaning Tower of Pisa

1. The Leaning Tower of Pisa is located in the Church Square of Pisa, an ancient city in western Italy. This is the bell tower of Pisa. The main church complex is also the most famous building in the complex. 2. The Leaning Tower of Pisa was built in 1174 and completed in 1350. It is entirely made of marble. The tower was erected at first, but on the third floor, because the foundation was not deep and the strength of the upper floor was low, the tower began to tilt and the project was suspended. Construction was resumed after 1994, and a series of anti-tilt measures were strengthened. However, after the entire tower was completed, the center of the tower top still deviated from the vertical centerline.

Currently, the center of the top of the tower.
