Effect of Spall on the Characteristics of Explosive Ground Motion.

Abstract

An empirical technique is developed for predicting the vertical and horizontal extent of spall in soil or rock due to near-surface chemical or nuclear explosions. One-dimensional numerical analyses are presented describing multiple spalls in a tensilely weak, hysteretic material with a free surface. Theoretical analyses of the pore air effect are presented. They show that a fundamental understanding of soil spall requires an effective stress approach. (Author)
