基于标准化的公路简支钢桁梁桥设计创新与应用

The Design Innovation and Application of Standard Simply Supported Steel Truss Bridge

沾淄高速沿线跨河跨渠部分大跨径桥梁采用下承式简支钢桁梁,跨径布置有96 m、108 m和130 m三种,横向布置有三片桁和四片桁两种。现介绍了该项目的总体布置和结构设计,归纳总结了基于标准化设计和制造的公路简支钢桁梁桥设计难点和技术创新,可为今后同类桥梁设计提供参考。

The long-span bridges across canal along Zhanhua to Linzi Freeway are simply supported through truss steel bridge.The span layout includes 96 meters,108 meters and 130 meters.This paper introduces the general layout,structure design,and summarizes the design difficulties and technology innovation,which could provide reference for other similar bridges.
