【摘要】 采用有限元方法对深井巷道掘进过程中爆破振动对围岩影响进行了数值模拟,对单元峰值有效应力进行分析,结果表明,数值模拟能够揭示岩石内部的损伤情况,反应岩石内部爆破应力分布规律,研究结果对巷道爆破掘进施工和支护设计具有工程指导意义。更多还原

【Abstract】 The finite element method is used to conduct numerical simulation of Blasting vibration in the process of blasting excavation for deep well laneway and to make regression analysis based on the peak effective stress.The results show that the numerical simulation can reveal the blasting situations of the rock within,and reveal the rules for the rock blasting stress distribution,which has guiding significance for blasting excavation of laneway and timbering design.更多还原
