摘要
本文依物理学基本定律对不同装药结构进行分析,给出了耦合装药在冲击荷载超过岩石变形曲线上的临界应力时,按冲击波理论计算孔壁压力;否则,按弹性波理论来计算;不耦合装药时按弹性波理论计算。
Based on the physical fundamental equations, this paper analyses diffrent kinds of charge constructions. When shock stress on the hole wall exceeds cirtical stress on curve of rock deformation, the pressure on hole wall should be calculated according to shock wave theory, otherwise,according to the eastic wave theory.
