摘　　要：基于香溪长江公路大桥混凝土拱座与钢箱拱结合部为受压构件的特点,采用改进的承压板方式进行连接设计,阐述了结合部的设计思路及局部设计细节,确保结构安全可行;通过钢-混结合部的有限元计算,对各个构件进行了分析,并根据计算结果,对结合部进行了优化设计。In the light of the characteristics that the joint parts between the concrete saddle and steel box arch ring of Xiangxi Yangtze river bridge mainly work as the compressive elements,the combined section are designed by means of improved bearing plate, the design ideas and local design details of combined section are analyzed to ensure the safety of the structure. By means of finite element calculation, the various components are analyzed in detail. According to the calculation results, the design of combined section is optimized.
