摘要
针对简支梁式架空轨束梁架空跨度小、跨中挠度大的不足,按连续梁架空方式设计了一种跨度达8.7 m,最大挠度仅为9 mm的轨束梁,经检算和实际使用均满足施工要求。同时,提出一种检算轨道架空横向稳定性的方法。
This paper aims at the shortage of built on stilts rails simple beam in the aspect of span smaller and deflection larger,designs a built on stilts rails continuous beam,its span is 8.7m and deflection only 9 mm.The continues beam can meet demand both design and practice.Besides,author also presents a new method of examining the cross stability of built on stilts rails beam.The method in this paper provides very useful reference for the design of built on stilts rails beam.
