摘　　要：针对爆破中提高爆破质量和更好保护周围环境的问题,利用有限元软件ANSYS/LS-DYNA,动态模拟柱状装药的爆破冲击过程,从等效应力云图和主应力-时间历程曲线分析,探究柱状装药爆炸中爆轰方向对应力波和主应力的影响情况,得出了柱状装药爆破中可用炸药爆轰方向来调整作用于岩体破碎能量的结论。To improve blasting quality and environment protection,the finite element software,ANSYS/LS-DYNA,was used to dynamically simulate the blasting process.Equivalent stress cloud chart and principal stress-time course curve were analyzed to explore the effect of detonation direction on stress wave and the principal stress in column charge.The conclusion is that the detonation direction can be used to adjust rock broken energy in the column charge explosion.
