摘要
与常规铁路隧道不同,客运专线铁路隧道设计除了要考虑满足围岩稳定性、建筑限界等外,还必须考虑高速列车在隧道中运行时所诱发的空气动力学效应的影响。文章通过遂渝线200km/h提速综合试验中的隧道气动力及结构动力学试验,对200 km/h动车组通过隧道内和列车上瞬变压力、空气动力荷载、列车风、微气压波等进行分析与研究,从而为时速200 km/h客运专线隧道的设计提供依据。
Unlike the tunnels on conventional railways, tunnels on special railway lines for passengers should be designed to take into consideration the aerodynamic effect induced by the high speed trains passing through them beside the requirements of rock stability and clearance limit. Based on the aerodynamic and structural dynamic experiments in the comprehensive experiment for 200km/h trains on Suining-Chongqing railway line, the paper analyzes and studies the transient pressures inside the tunnel and inside the train, aerodynamic loading, traffic wind, micro air pressure wave etc. caused by the rolling stock passing through the tunnel with a speed of 200km/h, thus offers a basis for the design of tunnels on special railways for passengers.
