AbstractThe subway station is an easy target for terrorists. In this paper, AUTODYN software is used to simulate the characteristics of shock wave propagation in the subway station. Further, the effects of walls, standing columns and stairs on the shock wave propagation are analyzed quantitatively by setting reference points in the subway station. According to the over-pressure distribution of the explosion at subway station, the casualty distances and the favorable positions for personnel to hide are determined. The results show that the shock wave in the subway station is affected not only by the reflection of the whole structure, but also by the diffraction and local reflection of the platform columns. Due to the pressure relief on the shock wave by the stair exit, the overpressure peak on the stair slope is greater than those at other locations near the stairs at the same explosion distance.
