建立了考虑节理粗糙度与法向应力的节理峰值剪切位移计算新公式。
The results show that there is a negative relationship between peak shear displacement and joint roughness but a positive relationship between peak shear displacement and normal stress.
通过将界面粗糙度定义为等效起伏角，模型能模拟节理循环剪切性状。
After the joint roughness is defined as the equivalent inclination Angle, the model can simulate the behaviors of joints under cyclic loading.
