摘要
对拉西瓦花岗岩在各种受力情况下岩石破坏断口,进行了微观扫描电镜试验研究,分析了岩石微观破坏形貌特征和微观破坏力学机制。通过试验研究和理论分析,明确地给出了高地应力地区钻孔岩芯饼状破裂和岩爆产生的微观破坏机制,为进一步分析高地应力地区脆性围岩岩爆产生的机理提供了可靠的实验依据。
For Laxiwa granite failure surface under various stress states, the microtest has been carried out to study the microfailure character and its mechanism. Based on the test and study, the mechanism of borehole core disking and rockburst is obtained.
