两种计算方法下斜腿刚架桥的受力变形分析

Analysis on force and deformation of slant-legged rigid frame bridge under two computing methods

以某跨线桥为例,采用三维有限元模型分别计算了强迫位移法和结构与土共同作用法的受力与变形,并对两种计算方法进行了对比分析,得出一些有意义的结论,为类似工程的设计提供了依据。

Taking a certain flyover as an example,the author separately calculates force and deformation by forced displacement method and structure-soil combined action method with 3D finite element model,carries out contrast analysis on the two computing methods,and draws some conclusions,in order to offer a reference for the design of similar construction.
