Abstract : A NATO munitions storage facility at Machrihanish, Scotland has armaments stored in aboveground magazines. The magazines are surrounded of 3 sides by earth berms. A mass explosion is simulated in a 1/23.5 scale model of this facility using a 1 kg bare hemispherical Pentolite charge to model the full scale mixed explosive load. The charge is detonated with a responding concrete donor structure, and measurements are obtained from pressure sensitive transducers mounted in a neighboring non-responding steel model. Visual evidence of the blast loading is obtained from a responding concrete acceptor structure. All models are surrounded on 3 sides by coarse sand berms or hardpacked soil berms. It was determined that sand berms attenuate the blast pressure more than hardpacked berms. The confining effects of the donor structure significantly reduced the blast pressure. Positive phase impulse was not significantly reduced by altering the berm material or confining the charge.
