CB100(CB321)Bailey Bridge
BAILEY
Design phase
1) Reasonable site selection: Consider geographical environmental factors such as terrain, water flow, soil conditions, etc., to ensure the stability and durability of the bailey bridge and reduce damage to the surrounding natural environment.
2) Material selection: Based on the structural form, stress state, connection method, and environmental conditions, materials should be selected reasonably, with priority given to environmentally friendly, recyclable, or reusable materials.
3) Component standardization: Components should be standardized and universal, facilitating production, installation, inspection, maintenance, disassembly, and reuse, reducing material waste and environmental impact.

Case presentation
321 type Bailey bridge: It is a rapidly assembled bridge developed in China based on the original British Bailey truss bridge and combined with national conditions. It was finalized and produced in 1965 and widely used in national defense, transportation engineering, and municipal water conservancy engineering. A set of equipment can be used to construct single lane bridges with spans of 9, 12, 15... 60, 63 meters, capable of carrying loads of 10, 15, 20, 50 tracks, and 80 trailers.
