摘　　要：通过对球形装药土中爆炸的数值模拟，研究了球形装药半无限土介质中爆炸作用下，土介质的动力学响应；空腔的形成发展规律及鼓包的运动规律等动力学问题．数值模拟结果与实验现象吻合较好。A method of nUmerical simulation of underground explosion process of sphericalchargeS is used to study some dynamic problems, such as the nsponse of soil medium dynamics, the formation and development of cavity, the motion law of cupola during explosion of thecharge in semi-infinite soil mediUm. The resultS of nUmerical simulation agree well with the experimental phenomena.
