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.
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。
it is verified through direct shear tests in which joint roughness and normal stress are the two major factors influencing joint shear displacement.
试验结果表明,峰值剪切位移与节理粗糙度成反变化关系,与法向应力成正变化关系。
after the joint roughness is defined as the equivalent inclination angle, the model can simulate the behaviors of joints under cyclic loading.
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。
a simpler fractal model to estimate the joint roughness coefficient (jrc) is suggested. it can be applied to simulate rock discontinuity profiles.
提出了一种更为简单的估算巖石断裂面粗糙度(jrc)值的分形模型,可用来模拟巖石断裂面剖面线。
