摘要
客运专线铁路隧道的设计与研究中必须要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,其中应重点考虑瞬变压力对旅客乘车舒适度的影响。文章通过遂渝线提速(200 km/h)综合试验中的隧道空气动力及结构动力学试验,对200km/h动车组通过隧道时隧道内瞬变压力的现场试验数据及其单维效应进行了分析与研究。
Aerodynamic effects induced by high -speed trains passing through tunnels must be considered in the design and research for tunnels on passenger - dedicated railway lines, in which the influence of transient pressure on the comfort degree of passengers must be considered in particular. Based on the aerodynamic and structural dy- namic experiments in the comprehensive test for rolling stock passing through tunnels with a speed of 200km/h on Suining - Chongqing passenger - dedicated railway line, the data of transient pressures measured in - situ and their single -dimensional effects are analyzed and studied in this article.
