Abstract

Abstract

The energy distribution for ground shock of explosion with different buried depths in soil is studied with numerical simulation method, and the coupling coefficient data is gained from test. The minimal scaled buried depth for close explosion in free-field is 2.0 m/kg1/3 gotten in the paper, there is much difference to the data 0.56 m/kg1/3 in Fundamentals of Protective Design for Conventional Weapons (TM5-855-1), and the reasons for difference are discussed. The coupling coefficient with impulse forms gotten in the paper is quite different to that with stress form in TM5-855-1, the range and object for using should be careful.
