摘要
针对地下工程岩体随着深度、含水状态的变化将表现出流变变形的现象,通过对深部围岩蠕变规律进行探讨,并基于工程流变力学理论和渗流力学理论,对含水率的变化对软岩蠕变变形规律及本构方程的影响进行了研究,结果表明含水率是影响岩石蠕变变形非线性程度的重要因素。
With the development of exploitation depth and the change in water content, the deformation of engineering wall rock is mostly rheology. Aimed at this phenomenon, the paper summarizes the creep law about the deep waU rock. And offers a study of the changes of water content works on the creep deformation law Of soft rock and its constitutive equation based on the-engineering theology mechanics theory and seepage theol. The result shows that water content is an important factor affecting non-linear property of soft rock creep.
