摘　　要：论文将分形几何理论运用到岩体结构面粗糙度的描述中,指出了以往粗糙度分形计算的不足:只是对某条曲线的分形计算,不能完全反映整个粗糙表面的几何形态。针对该问题,用一种能测量表面三维几何形状的测量仪,测得试样的表面形态,并引用立方体覆盖法,对试样结构面的表面形态进行了分形计算,所计算的分维数能反映整个结构面表面的粗糙情况。This paper applies fractal geometry theory in the description of roughness of rock structural surface and points out the deficiency in traditional fractal calculation of roughness,which is only for some curve and cannot completely reflect the geometric shape of the whole rough surface.To this problem,it measures sample surface configuration with a measuring meter that can measure 3D geometric shape and carries out fractal calculation for sample surface configuration with solid coverage method.The calculated fractal dimension can reflect the roughness of the whole structural surface.
