摘　　要：通过学习纸质载体图像的扫描原理及数字图像的数字化表达方式和存储方式,构建了基于纸质载体曲线的数字曲线生成算法。借助编制的交互式程序,完成了岩石结构面轮廓纸质载体曲线的数字化,并实现了岩石结构面粗糙度系数的数字化测量。最后通过对一条岩石结构面轮廓曲线的手工测量和数字测量的对比,证实了本文介绍的结构面粗糙度系数数字化测量方法的可靠性。Based on the study of scan principle of paper-based image,expression and save mechanism of bit-mapped image,this paper constructed the algorithm which can gets digital data of paper-based curve by scanning.A graphical user interface is created,which is used to digitize the outline of rock-mass＇s discontinuity and calculate the JRC values digitally.In this paper,the reliability of this digital measuring-method of JRC was illustrated by a comparison between manual and digital measurement of JRC values on a same outline.
