通过应力波与由节理刚度系数描述的预裂缝的相互作用分析,考虑预裂缝在爆炸应力波作用下的闭合效应及预裂缝充水等条件下,研究了预裂缝的隔震机制与隔震效果,从而为岩石开挖过程中周边控制爆破方式的优选提供了理论依据
Based on the analysis of the interaction between stress wave and the pre-fracture described by the joint stiffness coefficient, considering the pre-fracture closure effect under the action of explosion stress wave and pre-fracture water filling, the isolation mechanism and isolation effect of pre-fracture are studied , Which provides a theoretical basis for the optimization of surrounding controlled blasting methods in rock excavation
