Abstract：In this article, 6.5kgTNT is simulated to blow up with AUTODYN at the floor of a subway station. The propagation law of blast wave along the platform and the wave along the staircase plane and the lengthways of the station are analyzed to plot a Splash Radius contour of 1.5m high ground from the floor. It proves: In the subway stations, shock wave’s attenuation is slow, and the overpressure between the columns’ channel area is higher than that of the both sides open areas relatively. In the subway station of this paper, after the TNT blasted, there won't be casualties over about 20 m far from the TNT. Within about 12m far from the TNT, the casualties range line is irregular. The lung injury probability between the columns is higher than that of the both sides open areas relatively. The area within 4m far from the TNT is included in the 1% dead line, and the closer to charging center, the higher risk of death
