摘要
以通州通惠河桥为例,选取3种梁拱组合桥总体方案进行比选设计,采用空间有限元分析软件对桥梁上部结构进行整体计算分析,对关键部位的受力性能进行验算。综合考虑建设条件、道路规划、水文地质和现况管线等因素,确定了桥梁布跨形式及桥梁结构体系,最终采用非对称上承式梁拱组合桥方案跨越河道。
This paper takes Tonghui River Bridge in Tongzhou as an example,and selects three overall schemes of beam-arch composite bridges for comparison and design.The spatial finite element analysis software is used to calculate and analyze the overall structure of the bridge superstructure,and the mechanical performance of the key parts is checked.Considering the factors such as construction conditions,road planning,hydrogeology and current pipelines,the bridge span arrangement and bridge structure system are determined.Finally,the asymmetric deck beam-arch composite bridge scheme is adopted to cross the river.
