摘　　要：利用LS -dyna3D有限元程序 ,运用非线性动力学基本理论和算法 ,针对集团药包对半无限土介质中爆炸时空腔的形成和发展规律以及鼓包的运动规律等问题 ,进行了数值模拟研究 ,将模拟计算结果与现有实验研究成果进行了对比 ,并分析了数值模拟和模拟计算结果的正确性。A method of numerical simulation of underground explosion process of cylindric charges is used to study some dynamic problems by taking advantage of Ls-dyna3D, such as the formation and development of cavitation and the motion law of explosion cavitation, in accordance with cylindric charges explosion in semi-infinite soil medium. The results of numerical simulation are compared to the experimental ones. The results of numerical simulation and simulative calculation are analysed.
