Simulation of the Pressure Attenuation of Chemical Shock Wave in Long Tunnels

Li Xiudi~①,Zheng Yingren~①,Li Liesheng~②,Zheng Yunmu~①①Department of Architecture & civil Engineering,Logistical Engineering University(Chongqing,400041)②Airport and Barracks Department,Guangzhou Military Region Logistics office(Guangzhou,510052)  
In order to design efficient protective doors in tunnels,pressure histories inside the tunnel should be determined primarily.Based on Hopkinson scaling law,attenuation of shock wave peak pressure in long tunnels from conventional explosions outside the tunnel entrance is simulated with the dynamic finite element software of LS-Dyna.Simulated result is compared with other experimental results,and can be used as the basis to determine the chemical shock loads on the protective doors and the protective methods.
