摘要(Abstract):
岩石中含有以孔隙、气泡、微观裂隙、节理面等形态表现出来的岩石损伤。损伤的存在无疑要对岩石的爆破破碎效果产生影响。本文在相似性分析的基础上,提出了在实验室进行岩石爆破损伤模型实验的新方法,进而对损伤以及介质强度对爆破破碎效果的影响进行了分析研究。
In rock mass, there exists rock damage expressing in the form of small opening, air-bubble, fracture, cleavage etc. The damage will have effect on the process of wave travelling and result of rock fragmentation. Based on the simulation theory, the model experiment of blasting damage of rock carried out at laboratory is put forward, furthermore, the effect of damage and medium strength on the result of fragmentation are analyzed according to the damage simulation test.
