The explosion process of explosive in soil was analyzed by ANSYS/LS-DYNA software. The bulging movement process of explosion in soil is simulated by numerical calculation. Pressure distribution in soil near explosive, formation and effect of the stress wave, particle motion and stress-strain distribution Law in concrete slab were also studied.%采用ANSYS/LS-DYNA软件对炸药在土壤内部的爆炸过程进行了显示动力分析.通过数值计算,模拟了土壤中装药爆炸形成鼓包运动过程,研究了土壤中炸药近区压力分布、应力波的形成及影响、质点运动及混凝土板中应力一应变分布规律.
