| 摘 要： | 综合三种单一的斜拉桥索力优化方法,采用ANSYS优化模块进行求解,对成桥状态下最优索力的确定进行了分析,结果表明:采用索力优化三步综合方法,不仅可以同时考虑结合处的弯矩和恒活载的共同作用,而且优化得到的索力均匀,主梁上下缘具有足够的安全储备,结构变形较小,成桥状态更为合理。

| Abstract: | Through using three kinds of single cable-stayed bridge cable force optimization method,by using ANSYS optimal module for calculation,the article analyzes the optimal cable force determination under the finished bridge state.Results show that: applying comprehensive three-step cable force optimization method can not only consider the mutual function of junction bending moment and dead-live load,but also obtain even cable force,safe storage of upper and lower major beam,small structure deformation,and more rational finished bridge state. |
