摘要
基于列车脱轨能量随机分析理论,提出了预防列车脱轨的桥梁横向刚度限值分析方法。运用此方法,制定了提速线3×80 m连续钢桁梁桥横向刚度限值,为修订铁路钢桥设计规范提供参考。
Based on energy random analysis theory for derailment,a new method to analyze the limit value of bridge lateral rigidity for derailment prevention is established.Using this method,the limit value of lateral rigidity for 3×80 m continuous truss beam on speed-raised line has been built.The limit value of lateral rigidity for 3×80 m continuous truss beam established in this paper can provide reference for modification of design code.
