摘　　要：以沈阳市在建的南阳湖斜拉桥为工程背景,采用MIDAS/Civil软件进行有限元分析,实现了对斜拉桥成桥阶段和施工阶段索力的模拟计算。确定了一种综合方法得到合理的南阳湖桥成桥索力。应用正装分析方法对各施工工况进行了仿真,绘制出施工阶段的索力时程曲线,用于该桥整个施工控制过程。On the basis of Shenyang N anyanghu Cable - stayed Bridge which is being builded, a simulativecomputation is realized for finished-dead state and construction state , through the fini（e element analysis software MIDAS/Civil. The reasonable cable force of Nanyanghu Cable - stayed Bridge in the finished dead state by a comprehensive method is determined. Each construction stage is simulated by the forward analysis meth-od, and then the cable force time travel curve of the construction stage is drawed, in order to control the whole construction process.
