Equivalent Simulation of Soil Motion Characteristics under the Action of Ground Shock Induced by Nuclear Explosion

doi:10.3969/j.issn.1000-1093.2021.01.006

Abstract

Abstract: Nuclear explosion induces the problems such as multi-field coupling, strong nonlinearity and large deformation of rock and soil media, which makes the ground shock wave composition complex and difficult to simulate the ground shock effect of nuclear explosion accurately. In order to solve these problems, an accurate method for describing the combined effect of induced ground shock wave and direct ground shock wave is proposed, and a simulation analysis model is established. The method is used to simulate a ground motion test which was carried out by the U.S. Army. Ground shock waves induced by the overpressure shock front were obtained, which shows that the surface and subsurface targets are subjected to the effects of induced ground shock wave while being hit by the air shock wave, and the round shock effect of entire nuclear detonation is the combination of airblast-induced ground shock and direct ground shock. The simulated results of soil velocity fit well with both test data^［3］ and calculated values in TM 5-858-2^［8］, proving the validity of this numerical simulation model.
