摘　　要：运用三维离散元程序3DEC,对某露天矿高陡节理岩质边坡在自然状态下的静态响应和爆破载荷作用下的动态响应进行了模拟,分析了爆破载荷作用下边坡质点的振动速度以及位移和应力特征,并将计算结果与现场监测结果进行了比较。结果表明,两者吻合较好,用3DEC模拟爆破载荷作用下节理岩体边坡的动态响应是适合的。The static and dynamic response of high steep joint-rock slope under blasting load is simulated by Three-Dimensional Distinct Code （3DEC）. Vibration speed, displacement and stress field of given slope particle under explosion are analyzed and results obtained are compared with that from site monitoring. It is shown that the both are in a good agreement. Therefore, 3DEC simulation on the dynamic response of jointed rock slope is effective.
