Aerial China：Hunan Xiangxi Aizhai Bridge, built on the top of the canyon湖南湘西矮寨大橋，建在峽谷之巔

Aizhai Bridge is located in the northwest of Xiangxi Tujia and Miao Autonomous Prefecture, Hunan Province, China, above Dehang Grand Canyon, about 20 kilometers away from Jishou City. To Aizhai No. 3 Tunnel; Baotou-Maoming Expressway
The Aizhai Bridge consists of the main bridge, two bridge towers, cables, anchors, suspension rods, and connection tunnels; the main bridge section is arranged in the northwest to southeast direction.
The Aizhai Bridge adopts a unique artistic shape of the main structure. The cable towers and stiffened steel trusses built on the hilltops on both sides of the bridge are directly connected to the tunnel on the cliff. The beautiful natural landscape around is very harmonious; at the same time, the top of the bridge tower adopts the bull's head pattern, which is the worship object and mascot of the local people, symbolizing the people's modesty and kindness, strength and progress. The tensioned curved suspension cables are integrated to form a local landmark.
The main innovative technologies of Aizhai Bridge are:
1. Pioneered the new structure of tower and beam separation suspension bridge, realizing the perfect integration of structure and nature. It provides a very competitive bridge layout scheme for bridge construction in mountainous areas.
2. The high-performance rock anchor system using the new material "CFRP-RPC" has been developed, which solves the problems of large burial depth and poor durability of traditional rock anchors, and overcomes the problem of large-tonnage carbon fiber cable anchoring.
3. Developed structure and mountain system stabilization technology, carried out theoretical analysis on the stress and deformation of Chadong shore mountain and real-time monitoring of the whole process during construction, and demonstrated the stability of the mountain under complex stress conditions.
4. Pioneered a new technology for the erection of the main girder of suspension bridges by the "rail slip method", developed new equipment for the erection of the main girder of suspension bridges with the "rail slip method", and solved the problem of erecting main beams of suspension bridges in mountainous areas. It is recognized by the world as the main girder of suspension bridges. The fourth method of erection.
5. A new cable-type on-site wind observation equipment was developed, which solved the on-site observation problem of complex canyon wind fields and ensured the testing accuracy of the new equipment.
6. The achievements of the bridge have solved many difficulties in the design and construction of large-span suspension bridges in mountainous areas, and effectively promoted the development of bridge technology in mountainous areas. The project results have also been successfully applied to the Tiger Leaping Gorge Jinsha River Bridge and the Lvzhi River Bridge. Aizhai Bridge is adjacent to Shibadong Village, the first place of “targeted poverty alleviation”. With its excellent influence, the bridge increases local tourism revenue by more than 50 million yuan every year. It is a model project for the practice of targeted poverty alleviation.
