The Construction and Components Analysis of The Aizhai Bridge

Abstract

The Aizhai bridge was constructed in a mountainous area and across a large canyon, a bridge that bears immense importance to the development of the nearby areas, according to the China Hunan Roads Development III Project. This study analyzes the structure, construction, materials, and components of the Aizhai Bridge, and discusses their advantages and drawbacks. Some novel construction techniques for the suspension bridge include aerial spinning and steel truss gliding method. Results show that the structural design is unique to the project, adapting to specific conditions such as complex geology, extreme weather, and large interval by implementing the design of tower-girder separation for the bridge alongside the design of the suspender cables and the materials implemented in the bridge, comparisons of carbon emissions due to materials are made with other bridges demonstrate the high effectiveness of the bridge design. Although the essence of the structure follows that of a traditional suspension bridge, the new design of the tower-girder separation structure has made the bridge much more environmentally friendly and safe.
