摘要：

The influence of enlarged section parameters on pressure transients of high-speed train passing through a tunnel was investigated by numerical simulation. The calculation results obtained by the structured and unstructured grid and the experimental results of smooth wall tunnel were verified. Numerical simulation studies were conducted on three tunnel enlarged section parameters, the enlarged section distribution along circumferential direction, the enlarged section area and the enlarged section distribution along tunnel length direction. The calculation results show that the influence of the different enlarged section distributions along tunnel circumferential direction on pressure transients in the tunnel is basically consistent. There is an optimal enlarged section area for the minimum value of the pressure variation amplitude and the average pressure variation in the tunnel. The law of the pressure variation amplitude and the average pressure variation of the enlarged section distribution along tunnel length direction are obtained.
