An underground storage facility can be very complicated. It may include multiple storage chambers, access tunnels, and exits. Prediction of the internal and external pressure environment, for developing explosives safety criteria, has been done with limited success. The Naval Facilities Engineering Service Center was tasked by the Department of Defense Explosives Safety Board to predict the internal blast environment for specific tunnel magazine tests. The dynamic pressure environment was calculated using AUTODYN-2D and -3D. Effects of tunnel geometry and media surrounding the tunnel on the load environment are presented and compared to test data.
