摘　　要：现针对钢—混凝土连续梁桥结合段的构造及受力特点来进行分析,以采用单箱四室断面的川周公路浦东运河桥为例,首先对其钢—混凝土结合部的设计思路进行了介绍。然后建立ABAQUS有限元模型,对钢—混凝土结合部进行实体单元受力分析,给出了有限元分析结果,并总结了受力特点。结果表明,钢—混凝土结合部的钢板、混凝土、剪力连接件等受力均能满足要求,同时,结合部通过后承压板和开孔剪力板连接件等,实现了从钢结构扩散传力至混凝土段。The structure and mechanical characteristics of the steel-concrete joint section of the continuous hybrid girder bridge is analyzed.Taking the Pudong Canal Bridge on Chuanzhou Highway(with a single-box four-cell cross-section)as an engineering case,the design methodology of the composite joint section is first introduced.Then,the mechanical property of the steel-concrete joint is Analyzed by ABAQUS with the solid element,the finite element analysis results are given,and the mechanical mechanical behavior are summarized.The results show that the steel plate,concrete and shear connectors of the steel-concrete joint can meet the requirements.Meanwhile,the joint realizes the transfer of force from the steel structure to the concrete section through the rear pressure plates and the perfobond rib shear connectors.
