博士学位论文摘要　 通过理论分析与建模、实验室与现场试验、数值模拟计算三个方面 ,深入探讨了岩石在爆炸荷载作用下的细观断裂机理及损伤演化规律 ,对爆破损伤岩石的力学特性进行了实验研究和分析。在分析研究现有岩石爆破损伤模型和岩石损伤断裂理论的基础上 ,提出了用宏观 PhD thesis Abstract Through theoretical analysis and modeling, laboratory and field experiments, numerical simulation calculation of the three aspects of the rock in depth under the action of explosion load of meso-fracture mechanism and damage evolution of mechanical properties of blasting damaged rock Conducted experimental research and analysis. Based on the analysis of existing rock blasting damage model and rock damage fracture theory,
