摘 要: 利用LS_DYNA程序,从岩土本身的力学性能、目标与炸药的位置、空气稀疏波的影响等多个角度出发,研究了岩土爆破中应力波的压力衰减以及爆破对地表混凝土结构物的影响,得到了其中的规律,为建筑结构的防护提供了一些思路与依据. The pressure attenuation of stress wave and the effect of blasting load on ground concrete structure in soil and rock blasting were investigated using LS_DYNA procedure in the aspect of mechanical properties of soil and rock, location of the goal and the explosives, as well as the rarefaction waves of air etc. Some laws are gained that can be used to the blasting resistant of structures.
