摘　　要：针对拱形斜独塔斜拉桥的结构形式和受力特点,结合工程实例,借助MIDAS有限元软件建立空间有限元模型,根据各施工阶段的结构体系和荷载状况,正确地模拟出各施工过程,对成桥索力进行施工仿真分析,以控制成桥线形的变化,使结构内力分布处于较优状态并满足设计和现行规范要求。Based on structural style and stress characteristics of arch single pylon cable-stayed bridge,combined with project case,spacial finite element model is established with the help of MIDAS finite element software.According to structural system and loading condition of each construction stage,each construction process is correctly simulated,and construction simulation analysis on hanger force of bridge is performed so as to control the linear change of bridge and make the distribution of internal force of structure in a good state and meet the requirement of design and current standard.
