joint roughness coefficient

基本解释

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岩石断裂面粗糙度（JRC）值的分形模型，可用来模拟岩石断裂面剖面线。
After that, the authors take Beishan of Gansu province for the HLW disposal area as the example, and measure the joint roughness coefficient(JRC) of surface rock mass and cores of borehole.
文章评述了现有岩体结构面粗糙度系数（JRC）的各种测定方法及存在的问题，分析了在高放废物处置库预选场址甘肃北山花岗岩地区，用“简易纵剖面仪”进行地表岩体及钻孔岩心裂隙结构面JRC的测量结果。
