The glass bridge in Zhangjiajie is famous, but is it really safe?

After many times of monitoring, Zhangjiajie glass bridge is safe. On the glass bridge with a total length of 430 meters and a width of 6 meters, 72 glass balls weighing 750 kilograms were placed irregularly, which objectively disrupted the pace of many pedestrians passing in unison and effectively curbed the vibration of pedestrians.

On June 25th, 20 16, the glass bridge of Zhangjiajie Grand Canyon, the highest and longest in the world, was inspected for safety. 2 tons of off-road vehicles rolled back and forth on the bridge deck glass, and more than 20 people slammed them with hammers in turn. More than 75 kg 10 young men jumped together. Even if the deck glass is "black and blue", the glass bridge as a whole is still "safe and sound".

Especially, in view of the technical problem that many pedestrians are prone to * * * vibration when they travel fast on the bridge, which leads to the deformation of the bridge structure, 72 glass balls weighing 750 kilograms were irregularly placed on the glass bridge with a total length of 430 meters and a width of 6 meters, which objectively disrupted the pace of many pedestrians passing in unison and effectively curbed the vibration of pedestrians.

Zhangjiajie Grand Canyon Glass Bridge is located between two alpine canyons in Zhangjiajie Grand Canyon Scenic Area. The designed main span is 430 meters, the bridge deck is 375 meters long and 6 meters wide, and the relative height of the bridge deck from the valley bottom is about 300 meters.

As the first bridge and tourist landscape project in the world, it has attracted worldwide attention since the concept of construction was put forward. After countless times of design, demonstration, material selection, and repeated experiments and tests, it has overcome many world-wide technical problems such as building material selection, wind resistance, anti-skid, compression resistance, wind resistance and frost resistance, and has been called "the model of bridges in the world" by bridge construction experts.

Extended data:

The deck glass of Zhangjiajie Grand Canyon Glass Bridge consists of three layers of laminated glass, with a total of 99 pieces of * * *, each with a specification of 3m×4.5m and a thickness of 15mm. Before being installed on the bridge deck, hundreds of load rolling tests have been carried out, and the most conservative bearing capacity is about 40 tons.

Chen Zhidong, chairman of Zhangjiajie Grand Canyon Scenic Area, said that the bridge deck glass has many characteristics such as "large size, high hardness, high thickness, wear resistance, anti-freezing, ultra-pure, explosion-proof, high load, anti-mildew and temperature drop resistance", so the public need not worry about safety issues.
