项目摘要
In this study, we experimentally and theoretically investigated mechanisms for scale effect on the mechanical behaviors of a rock fracture, and showed that the scale effect on the closure and shear behavior of a fracture under normal and shear stresses primarily depends on that on the standard deviation (SD) of the aperture. Furthermore, we proposed a method for estimating the hydraulic conductivity of a fracture with an arbitrary direction in the axes of principal stresses, and illustrated the variation in the hydraulic transmissivity with the direction of the fracture.
在这项研究中,我们从实验和理论上研究了岩石裂缝力学行为的尺度效应机制,并表明在法向应力和剪应力下,尺度效应对裂缝闭合和剪切行为的影响主要取决于标准差(SD) 光圈。此外,我们提出了一种估计主应力轴上任意方向裂缝的水力传导率的方法,并说明了水力传导率随裂缝方向的变化。
