摘　　要：首先分析了岩石节理的力学特性，简要介绍了确定节理粗糙度系数的几种方法，指出了这些方法中存在的一些问题．提出了以施密特锤平均回弹数、节理壁平均抗压强度、节理开度、节理面平均粗糙幅度等为基本因素，用模糊数学确定节理粗糙度系数的方法．该方法简单、可行．The mechanial characters of rock joint surfaces are analyzed at first. Some methods of determining JRC of rock joint are presented and some problems existing in thesemethod also pointed out. The computing JRC method with fuzzy mathematics taking themean rebound number from Schmidt hammer. mean joint compressive strength. averageaperture and joint roughness amplitude as the basic factors is finally put forward. Themethod is simple and feasible.
