摘要
以高速铁路隧道列车车内舒适度标准为依据,结合单维特征线法的计算结果给出了不同密封性能列车对应的瞬变压力超标隧道长度区间,并分析得出列车车速、车长和动态密封指数对超标隧道长度区间的影响规律和不存在瞬变压力超标隧道长度区间时动态密封指数应满足的要求,最后对相关设计工作提出了建议。
Tunnel length ranges with over-standard transient pressure of sealed trains were provided based on comfort criteria for high speed railway trains in tunnel and calculation results using single-dimensional characteristic line method.The influences of train speed,train length,dynamic seal index on over-standard tunnel length ranges were analyzed.The requirements of dynamic seal indexes for tunnel length ranges without over-standard transient pressure were discussed.Finally,advice was given for related design.
