摘要

    摘要
  • 摘要: 随着地下工程建设的发展，深部围岩力学性能及其稳定性研究显得尤为必要。取岩芯于某煤矿深部巷道，根据该矿巷道地下水的化学成份配制了化学溶液，以模拟深部地下工程的地下环境，将岩石试件置于上述化学溶液中养护60 d然后开展细观试验。试验结果表明深部地下水的化学腐蚀将降低岩石的强度，尤其对于层理发育的损伤岩体；高强岩石破坏过程非常短暂，破坏形式具有岩爆的倾向性。
    Abstract: With the development of the deep underground engineering, the researches on the properties and stability of deep surrounding rock are very necessary. The specimens are come from the deep roadway of a coal, and the chemical solution is prepared to simulate the deep environment. Then the specimens are cured in the solution for 60 days and testing. The experimental results show that the strength of the surrounding rock decreases under chemical corrosion, especially for damage fractured rock mass. The failure process of the specimens is very short, and the failure mode has rock burst tendency.
