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的制定方法。运用此方法,分别制定了提速线32 m和40 m上承式钢板梁的横向刚度限值。对比该限值与新规范限值可知,新规范限值基本上满足预防脱轨与列车平稳运行的要求。
Based on theory of random energy analysis of train derailment, a new method was put forward to establish the limit value of bridge lateral rigidity with which derailment on bridges can be prevented. Using this method, the limit value of lateral rigidity for deck steel plate girder bridges of 32 m and 40 m on speed - raised line was built, respectively. By comparing the limit value of present results and that of the code （TB10002.2-99）, it can be seen that the limit value of the code （TB10002.2-99） can prevent derailment and ensure the smoothness and comfort of moving train basically.
