摘要
本文首先评述了现有确定岩体结构面粗糙度系数JRC的各种方法,如Barton经典剖面法、直接量测法、表面粗糙参数法、伸长率法、幅度法等.随后重点介绍了近年来发展起来的用分维理论(Fractal)描述岩体结构面粗糙起伏特征方法的原理和计算结果.实践证明Fractal法是最有发展前景和成功的方法.最后还对JRC的应用和发展中的若干问题作了讨论.
This paper first reviews the various methods for determining the joint roughness coefficient (JRC) of rock masses. These include Barton profile method, direct investigation method, roughness parameter method,size range rate method,and telescopic method. Then,this paper lays special emphasis on Fractal method which has been developed in recent years,its working principles and the results of calculation of Borton profiles using Fractal. Fractal method is proved applicable to the irregular joint surface profiles. Finally,some problems of the application and reseach of JRC are discussed.
