水下钻孔爆破冲击波传播规律的数值模拟研究

The Numerical Simulation Research on Shock Wave Propagation of Underwater Drilling Blasting

本文根据工程实践,对水下深孔台阶爆破中冲击波的传播规律进行了数值模拟,研究了水下爆破冲击波的传播特点。结果表明:水下深孔爆破采用水介质作为炮孔填塞物能够起到填塞效果;采用中心起爆方式的水下爆破冲击波沿岩石与水介质交界面一定角度的方向上,压力峰值最大。

According to engineering practice, the numerical simulation of the propagation law of underwater deep hole blasting shock wave was made to study the propagation characteristic of underwater blasting shock wave. The results showed that, using water medium as blasting hole stemming could play a certain role, and the shock wave pressure peak of underwater blasting with center detonation was maximum in the direction of the rock and water interface at a certain angle.
