摘要
介绍了铁路快速抢修钢桥的基本结构特点,并采用ANSYS程序对成桥运营和利用铁路救援起重机进行架梁两种情况进行仿真分析,计算结果表明该方案是可行的,钢梁在架设及使用中是安全的。
The basic structural characteristics of the project for rush-repairing railway steel bridges are dealt with in the paper. A simulation analysis is made of the rush repairing of railway steel bridges respectively at the operation stage and the girder-erecting stage by using the railway wrecking crane, by means of the finite element analysis program ANSYS. The results prove the construction project feasible and the steel bridge safe.
