不同JRC岩石节理剪切力学性质研究
Research on shear mechanical properties of rock joints with different JRCs
摘要
Abstract
Ten standard jointed curve proposed by Barton is taken as the research foundation with the model of rock joint generated and direct shear tests under different normal stresses conducted by PFC.Relationship between JRC and the peak shear strength along with development rules of cracks at different JRCs and normal stresses are studied.The results show that test results of simulated joints correspond well with that observed from physical tests.The peak shear strength increases with the increase of JRC and normal stress.Micro-cracks are produced in joint and concentrated in larger fluctuation.The number of crack number increased with the increase of joint JRC and crack number increases linearly with the change of normal stress.关键词
