摘　　要：文章主要介绍了隧道压力波数值模拟软件的原理与应用。该软件以一维可压缩非定常流动模型为基础 ,采用特征线法计算列车通过隧道时产生的压力波及相关的空气动力参数。A numerical simulation software of the air pressure wave in a tunnel is introduced in this paper. Based on the model of one-dimensional compressible unsteady flow, the software can calculate the pressure waves produced by a train entering a tunnel and other related aerodynamic parameters by the characteristic line method. The calculated results are useful in determining the net cross-sectional area of a tunnel and the approaches to alleviate the pressure wave in a tunnel.
