摘要
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.关键词
