Numerical Simulation of Pressure Wave in Railway Tunnel Caused by Two Trains Crossing
2017
DEStech Transactions on Engineering and Technology Research
When high-speed trains pass through tunnels, especially in two trains crossing condition, it causes severe pressure fluctuations. The pressure fluctuations entered into the coaches may make passengers to suffer from aural discomfort. In addition, the internal and external pressure wave will also bring fatigue damage to vehicle body and parts. Although we can avoid the tunnel crossing case through traffic planning and operation, but in the line with large number of long tunnels or in the busy
