Abstract

This study was aimed at evaluating the effect of various geologic backfill and shock insulation materials on the behavior of buried structures. Conventional explosives were assumed to detonate at the same depth, and various stand off distances. Various computational capabilities were employed for estimating the relationships between the physical parameters of the problem and the structural behavior. 1 Introduction and background Structures can be protected from weapon effects by burial in soil or rock, and the geologic cover provides shielding from the explosively induced stress waves. Many previous studies provided mainly empirical information on the influence of soil cover on load transfer to the buried structures. In all close-in explosion cases, where shock waves hav
