摘　　要：中承式钢拱桥作为桥梁工程中的一种,既能满足交通需求又具备较高的观赏性。以某一钢拱桥安装施工为例,对“先拱后桥”和“先桥后拱”两种施工方案进行比选,并采用Midas/Civil软件对比选后的方案进行临时施工结构和钢拱肋的施工数值仿真模拟计算;最后通过现场施工应力与变形结果的监控实测值来验证仿真结果的正确性,进一步说明比选方案的可靠性。研究成果可为类似工程提供参考。As a type of bridges,the half-through steel arch bridge can not only meet the traffic demand but also have appearance attraction.Taking the installation and construction of a steel arch bridge as an example,the two construction schemes of building arch first and then bridge or building bridge first then arch are compared,and the Midas/Civil is used to simulate the construction of temporary construction structure and steel arch rib of the selected scheme.Finally,the correctness of the simulation results is verified by the monitoring and measurement values of the in-situ construction stress and deformation results,and the reliability of the comparison scheme is further explained,which provides a reference for similar projects.
