EFFECTS OF AIRBLAST ON UNREVETTED EARTH WALLS,
Abstract
Small charges of TNT and 20-inch shock tube were used in attempt to determine action and effects of aboveground nuclear detonations that cause failure of excavated earth faces. Complete failure of full-scale foxhole with one detonation was not achieved. Spallation in walls occurred only after soil had been weakened by cracks developed by tensile stresses, drying, or both. Failure in model foxholes was observed only at high soil moisture content. Model failure on small scale using naturally occurring soil, as attempted in this study, was not feasible. This report is of interest primarily to investigators who attempt to simulate effects of airblast-induced ground shock from nuclear explosions. (Author)
