| Abstract: | The transient pressure variations in the tunnel and the carriage are simulated by using three-dimensional numerical simulation method and dynamic mesh technique when the train passes through the middle ventilation shaft in the urban subway tunnel.Based on the simulation results,the characteristics of the transient pressure variation in the carriage are analyzed under different train speeds and different sealing performance of the train.At the mean time,the conditions are achieved if necessary civil engineer... |
