| 摘 要： | 节理岩体经常受到地震、爆破等动载荷的作用，在动载荷作用下的稳定性经常是结构安全的关键。只有对节理岩体的动力响应有本质的理解，才有可能对岩体工程的动力稳定性进行合理的评价。在常规离散元法的基础上提出了动力离散元法的思想及计算方法，并编制了计算程序DDEM,最后给出了该方法在岩体动力学中的应用实例。

| Abstract: | Jointed rockmass are often subjected to dynamic loading, such as earthquake and explosion. Dynamic stability of engineering structure in jointed rockmass forms the key to structure safety. Only an essential understanding of dynamic response of jointed rockmass can enable a reasonable assessment of dynamic stability in rockmass engineering. Based on conventional discrete element method, the idea and calculating method of dynamic discrete element (DDEM) is proposed in the paper and a relevant program is developed. Some practical applications of the method in rock dynamics are presented. |
