市政双层交通桥梁结构体系选型

Structural System Selection of Municipal Double-deck Traffic Bridge

摘要:

基于节约用地以便为城市发展腾出更大空间的设计理念，许多市政工程采用了双层桥梁的结构形式。对常见市政双层交通布置在桥梁结构体系中的实现方式进行了梳理、总结与拓展，并结合工程实例介绍了双层桥梁的结构选型思路，可为类似桥梁设计提供参考。

Abstract:

Based on the design concept of saving land to make more space for urban development, the structural type of double-deck bridge is used in many municipal projects. The realization way of the common municipal double-deck traffic arrangement in the bridge structure system is sorted out, summarized and developed. Combined with an engineering case, the structural selection idea of double-deck bridge is introduced, which can be referred for the design of the similar bridges.
