摘要:
文章基于岩石材料的HJC本构模型，采用显式动力分析软件ANSYS/LSDYNA，模拟了深水岩石钻孔爆破水中冲击波的传播过程，分析了不耦合系数对不同方向上冲击波传播特性的影响。结果表明：不耦合系数对水中冲击波峰值压力和比冲量都有重要影响；在不同的方向上，比冲量随距离的衰减规律是不同的，其大小受不耦合系数也即装药量的影响较大。
Abstract:
Based on the HJC constitutive model, the variable process of shock wave in water for deep water rockdrilling blasting was simulated by the numerical program ANSYS/LSDYNA, and the influence of decoupling on propagation of shock wave in water was analyzed in the paper. The simulation results suggest that decoupling has significant effects on the peak pressure of shock wave in water and unit impulse. The attenuation characteristic of unit impulse with distance is different in different directions. Moreover, the decoupling has great influence on the value of unit impulse.
