摘要
对钢箱梁的布置形式、受力特点、适用情况进行对比分析,结合某装配式箱梁桥工程,对桥梁顶推施工过程中,各结构部件的受力进行分析,包括前导梁构造与主梁连接分析,主梁的变形和受力特性分析以及不利工况下的应力验算。
The arrangement form,stress characteristics and application of steel box girder are compared and analyzed in this paper.Combined with a prefabricated box girder bridge project,the stress of each structural component in the bridge jacking construction process is analyzed.It includes analysis of leading beam structure and main beam connection,analysis of deformation and stress characteristics of main beam and stress checking under adverse working conditions.
