| 摘 要： | 基于不规则的人工岩石节理经历不同剪切变形历史的剪切试验，分析了岩石节理剪切变．形特性及与变形历史的依存关系。结果表明，岩石节理峰值和残余剪切应力随垂直应力的增加呈线性增长趋势，而剪胀特性已变得不明显。两类节理面在经历不同垂直应力下的剪切变形历史后，剪切应力均不再出现尖峰；而不同剪切变形历史主要影响节理的剪切强度，对剪胀特性影响较小。

| Abstract: | Based on the shear tests of artificial rock joints under different shear deformation histories, the shear properties of rock joints are analyzed. The test results show that the peak and residual shear stresses increase linearly with the increase of different normal stress histories. Different shear displacement histories mainly affect the shear strength of joints, and have a little relationship with the dilatancy property of rock. |
