摘　　要：通过对不同含水状态页岩岩样三轴蠕变实验结果和与实验结果相符合的蠕变模型参数进行分析,得出了含水状态对岩石蠕变影响的规律,并对影响岩石蠕变的因素进行了探讨,结果表明,含水率和应力差是影响岩石蠕变的重要因素.The law of how the water content affecting the mechanical properties of rock creep was got through analysing of the results of virtual three axial creep testing of shale specimens in different water content and the parameters of rock model that coincides with creep testing results. And the factors of effect on rock creep were studied, The results show that water content and stress difference are the important factors affecting rock creeping.
