摘要
根据节理表面的接触特性提出了一个节理几何特性的新参数──节理吻合系数 JMC。实验显示,节理吻合系数是描述节理孔隙、形变、刚度、剪切强度和水渗导等特性的 重要指标。因此,将节理吻合系数和原有的节理粗糙系数相结合,可以更全面地描述节理的 几何特性,进一步估测岩石节理的水力特性。
A new joint matching coefficient JMC, based on the percentage of joint surfaces in contact is proposed as an independent joint surface geometrical parameter. Studies show that the JMC, together with the existing joint roughness coefficient JRC, governs properties of the rock joint. The studies demonstrate that joint matching is an important factor governing the aperture, normal closure, stiffness, shear strength and hydraulic conductivity of the joints. Therefore, JMC and JRC may be adopted for the engineering practice to estimate and predict the hydromechanical properties of rock joints.
