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 ftcube root kt3 in a wide variety of media.
