| 摘 要： | 为研究多孔爆破条件下的岩体破碎和爆破振动,采用完全重启动数值模拟方法和拉格朗日算法计算岩体爆破破碎过程,获得了岩体特征点的爆炸振动数据,对数值模拟和现场监测特征点振动速度进行对比,二者比较吻合. 研究结果表明,采用拉格朗日算法和完全重启动数值模拟方法可以较好地描述多孔岩体爆破过程中各起爆段别破碎和振动情况.

| Abstract: | To investigate smash of rocks and vibration of large-stiff slope under multi-hole blasting, full restart method of numerical simulation and Lagrangian formula were taken to simulate the smash of rocks and vibration of slope. The simulations show agreement with the experiments. The results indicate that full restart method of numerical simulation and Lagrangian formula can simulate multi-hole blasting vibration of large-stiff slope well. |
