摘　　要：该文借助分形理论对岩体结构面JRC的分形特征进行定量描述 ,以小尺度的量测结果来反映大尺度范围内岩体结构面JRC值的理论公式 ,从而消除JRC和结构面抗剪强度的尺寸效应 ,较为真实地反映岩体结构面JRC的实际状态 ,获得客观。With the aid of fractal theory, the quantitative description of the JRC fractal characteristics of rock mass structural plane has been conducted To reflect the theoretical formulae of JRC value of rock mass structural plane in large scale extent from the measured results of miniature scale, that eliminates the scale effect between JRC and the strength of structural plane, comparatively reflects really the practical state of JRC of rock mass structural plane, and the objective and real mechanical parameters of rock mass structural plane are obtained
