Prediction of Airblast Overpressures from Underground Explosions
Abstract
Two methods are presented for predicting airblast overpressures from underground chemical explosive and nuclear detonations. The first method utilizes empirical scaling techniques to predict both ground-shock-induced and gas-vent-induced overpressures. Empirical procedures are also provided for predicting airblast from underground row-charge and array detonations and from surface or near-surface bursts. The second method uses peak vertical spall velocities combined with basic physical principles to predict ground-shock- induced overpressures. Between these two methods, it is possible to predict airblast overpressures caused by detonations at scaled depths of burst from zero to 700 ft/cube root kt/3 in a wide variety of media.
