摘　　要：因现有铁路钢桥设计规范的计算方法不能完全满足新型抢修钢梁的设计需要,指出进行计算机仿真分析探讨的必要性。通过采用ANSYS程序对新型抢修钢梁某方案进行结构分析,得出对应急桥梁结构设计有用的结论,证明了有限元计算方法的可行性和适用性,可促进应急钢桥设计水平的提高。The computational methods in the ＂Code for Design of Railway Steel Bridges＂ are unable to meet the requirements of the structural calculation of new types of the railway breakdown steel beams. It is necessary to develop a new approach to the simulation. The structure analysis of one scheme is processed by ANSYS and the available conclusion is deduced. The feasibility and applicability of the finite-element method is also analyzed. The result of our research will improve the design of emergency relief steel beams.
