| 摘 要： | 对处于复杂环境下深部页岩蠕变特性进行试验研究,考察了在温度-应力-化学三场耦合作用下深部页岩蠕变特性的温度效应和pH值化学效应,并探讨了作用机理。研究结果表明,深部页岩的温度效应和pH值化学效应是明显的,而且pH值化学效应比温度效应更为显著;温度越高,页岩蠕变特性越明显,试验结果对当地煤矿井下的安全生产有参考价值;pH值越高,其蠕变特性越显著。

| Abstract: | Experimental research on creep behavior of deep shale under complex environment was conducted. Based on the testresults,temperature effect and pH value chemical effect on creep behavior of deep shale under thermalmechanical chemical coupling effect were revealed, and corresponding mechanisms were investigated. The research shows that temperature and pH value chemical effect of creep behavior on deep shale are obvious, and pH value chemical effect is more obvious than that of temperature effect; the higher temperature, the more ohvious creep behavior. The research results have reference value for local coal mine safety production environment. The higher pH value is, the more obvious creep behavior becomes. |
