Dynamic Properties Analysis of Soil under Blast Impact
Explosions produce shock waves that threaten the safety of facilities and equipment. The dynamic effects of shock
waves on soil are a crucial concern in terms of pipeline safety and protection. To further disaster prevention, this study verified
the results of field blast experiments using simulations. Simulations were conducted to examine the change in shock wave
transmission properties over time and space. In addition, the strain and displacement of soil upon sustaining impact were
examined. The results of these analyses can benefit engineering safety design and, ultimately, the safety of facilities and
equipment. The study results also revealed that fluid-structure coupling numerical models can be used to effectively analyze
fluid dynamics, examine the coupling effect in solids, and solve dynamic analysis issues such as geometric, material, and
contact nonlinearity. The results serve as a reference for those designing protection for the soil overburden layer.
