Effectiveness of Portal Barricades for Underground Storage Magazine

Abstract

To investigate a new method which can reduce hazard distance by accidental explosion in underground ammunition storage facilities, several hazard reducing devices were reviewed. The portal barricade in front of the portal was one of the IBD reducing devices studied. To investigate the effectiveness of portal barricades, a series of tests were conducted with concave shape portal barricades. It is found that concave shape portal barricades deflect blast wave exiting from the portal to upward direction, the blast pressures along the extended centerline axis of the tunnel are decreased, and IBD area is similar to a circle centered at the portal. IBD reduction along the centerline axis of the tunnel by the concave shape portal barricades is more than 55%.
