摘　　要：岩体结构面粗糙度系数JRC是描述岩体结构面粗糙起伏状态的力学参数,对于无填充或少填充的硬性结构面而言是关键性指标。本文介绍了岩体结构面粗糙度系数JRC估算方法的理论及应用研究现状,并探讨了JRC研究中存在的几个问题。The joint roughness coefficient(JRC) is the strength coefficient which describes the undulating shape having the impact to the joint shear strength,and it is understood that the JRC is critical to the joints which with without filling or with rare filling. In this paper, the techniques, advances, problems and likely future developments in researching methods for JRC has been presented.
