基于影响矩阵法的非对称斜拉桥索力优化分析

Analysis of the cable force optimization of asymmetric cable-stayed bridge based on influence matrix method

采用影响矩阵法进行索力优化能在斜拉桥设计与施工的索力调整中得到较好的效果,然而在实际工程中该方法的求解过程需要较高的理论基础,需要借助有限元软件。以实际工程为背景,通过有限元软件验证了基于影响矩阵法优化非对称斜拉桥成桥索力的可行性,并得出了一些有意义的结论。

Using influence matrix method to optimize the cable force can get better effect in the design and construction of cable-stayed bridge.However,the solution process of this method needs higher theoretical basis in practical engineering and the help of finite element software is needed.In this paper,based on the actual engineering background,the feasibility of the cable force optimization of asymmetric cable-stayed bridge based on the influence matrix method is verified by the finite element software,obtains some beneficial conclusions.
