【摘要】 在对三种岩石结构面进行直接剪切试验的基础上，探讨了结构面的变形特性和表面粗糙度的效应。发现残余抗剪强度与峰值强度之比与结构面粗糙程度之间有较强的相关关系。更多还原

【Abstract】 Direct shear tests were conducted with three kinds of rock joints that contained in limestone from a underground mine,deformation behavior and roughness effect of the joints are discussed.The shear force vs. shear displacement cerves are roughly liner.It is found that strong correlation exists between the ioint roughness and the ratio of the residual peak shear strength.更多还原
