Two-dimensional axi-symmetric Euler equations are solved in order to simulate the compression wave induced by a high-speed train entering a tunnel or a tunnel entrance hood. Pressure and pressure gradient histories at the tunnel entrance obtained from the calculation are compared with experimental results. It can be found that calculated results and experimental results are well corresponding each other. The effect of the cross-sectional area of the tunnel entrance hood is numerically investigated by this calculation method. Then, propagation of the compression wave along the tunnel is one-dimensionally calculated by a double mesh method which induces little numerical diffusion.
