Research on propagation law of blasting shock wave in subway station

The subway transportation has been widely applied all over the world as its unique advantages. Subway station is commonly charactered by dense crowd and closed environment, terrorist explosion in subway station would cause enormous losses of people life and property. In order to reappear of the subway station explosion failure process, a numerical model was established, and internal explosion responses were studied. Finally, the propagation law of blasting shock wave in subway station space was obtained. The results provide evidence for making emergency plan corresponding to terrorist explosion assault in subway station structure.
