Research on digital measuring of joints roughness coefficient of rock mass

WANG Wei1,2,WANG Xiaocui1(1.Zhejiang College of Construction,Hangzhou 311231,China; 2.School of Civil Engineering,Tongji University,Shanghai 200092,China)  
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.
