摘　　要：深溪沟大桥为中承式钢管混凝土等截面悬链拱桥。在充分考虑拱肋混凝土对称与均衡加载的基础上,采用MIDAS/Civil 6.71对整个混凝土灌注过程进行仿真计算,得出每一阶段结构的变形、受力特点和稳定系数,并讨论了结构的安全性。The Shenxi Gully Bridge is a half-through concrete-filled steel pipe arch bridge in uniform catenary. In this paper, based on the full consideration that the concrete to be poured into the steel pipe arch rib of the Bridge is loaded symmetrically and equilibriously, the simulation calculation of the whole process of concrete pouring for the arch rib is made by means of MIDAS/ Civil 6.71, the structural deformation, mechanical behavior and stability coefficients at each concrete pouring stage are obtained and the structural safety of the Bridge is also discussed.
