摘要

高速列车突入隧道会在隧道端口引起微压波,影响周边环境,而洞口微压波与初始压缩波紧密相关。文章对比分析了计算初始压缩波的三种理论研究方法的特点,并采用计算时间较短的三维解析方法对高速列车突入隧道产生的初始压缩波进行数值模拟研究。通过与国外实验结果对比,验证了计算方法的正确性,并研究了列车头型对初始压缩波的影响特性,为高速列车和隧道设计提供参考。
        The high-speed train entering the tunnel will cause the micro-pressure waves at the tunnel port,affecting the surrounding environment,and the micro-pressure waves at the entrance are closely related to the initial compression wave.This article analyzes and compares the characteristics of three theoretical research methods for calculating the initial compression wave,and uses the three-dimensional analytical method with short calculation time to numerically simulate the initial compression wave generated by the high-speed train entering the tunnel.By comparing with the experimental results abroad,it verifies the correctness of calculation method,and studies the influence characteristics of train head shape on the initial compression wave,which provides the reference for high-speed train and tunnel design.
