摘要
本文分析了节理的表面形貌特征,研究了不同形貌成分对节理剪切强度的不同作用,提出了能适用于3种不同表面形貌特征的节理剪切强度公式,并分3种情形建立了节理的闭合变形模型。对节理组合形貌含有周期性波纹度的节理的闭合变形模型也作了探讨。
Based on the analysis of the topographical characteristics of joint surfaces, the different effects of various components of surface topography on its shear strength are studied. The joint shear strength formula for three kinds of joint surfaces with different topographical characteristics is put forward. The closure deformation models for joints in three states are established.
