摘要:
文章以连续介质力学和动力非线性有限元理论为基础，推导炸药、水底介质和水的多物质ALE（multimaterial arbitrary lagrangian eulerian）控制方程，采用多物质ALE算法模拟了水下深孔爆破产生的水中冲击波、水底介质中应力波及爆破振动传播过程，并模拟了装药不同位置起爆时对爆破危害效应的影响。不同起爆方式产生水中冲击波由小到大的顺序为：顶端起爆，两端起爆，中间起爆，底端起爆；而爆破振动由小到大的顺序为：底端起爆，中间起爆，顶端起爆。
Abstract:
Based on the principle of continuum mechanics and dynamical nonlinear finite element theory, the multimaterial Arbitrary Lagrangian Eulerian (ALE) governing equations of explosives, soil and water in the underwater bored blasting system was derived. Multimaterial ALE finite method was applied to simulate the propagations of shockwave in water, stress wave and vibration in soil in underwater drilling blast, and the harmful effect of blasting when ignition at different charge areas.The simulation results of different ignition mode was like the follows:the sequence of shockwave in waterfrom little to large was top ignition, both sides ignition, middle ignition and bottom ignition, while the sequence of vibration from little to large was bottom ignition, middle ignition and top ignition.
