摘　　要：在抢修钢梁设计中,稳定性问题至关重要。介绍了32m铁路新型抢修钢梁的结构特点,分析了影响铁路中等跨度抢修钢梁整体稳定性的因素,通过有限元分析计算说明新型铁路中等跨度抢修钢梁的稳定性是满足规范要求的。Stability is of great importance in the design of steel beams for rush repairs. In the light of the structural characteristics of the new 32-m railway steel beams for rush repairs, factors influencing the integral stability of the medium-spanned railway steel beam are analyzed by means of the finite element method in the paper, the result of which shows that the stability of the medium-spanned railway steel girder is up to the requirements in stability of the Technical Specifications.
