摘　　要：基于DDA程序,引入JWL状态方程和空腔半径计算公式规范爆炸荷载的计算和加载问题,模拟岩石中爆炸成坑过程,利用该方法进行爆坑模拟案例分析,结果表明:该方法得到的结果与工程实践中观察到的现象吻合,研究思路具有可行性。Abstract： Based on DDA program （ Discontinuous Deformation Analysis）, the paper leads JWL equation of state and radius of cavity to regulate the calculation and loading of the explosion cratering process, simulates the explosion eratering process of the rocks, undertakes the explosion cratering cases by adopting the method, proves by the result that the results of the method is consistent with the observation in the engineering practice, so it is feasible for the research.
