摘　　要：分析了节理面产生的破坏机理和产生条件;从工程地质以及岩石和结构面的强度关系着手,利用 Mohr-Column 原理,推求岩体中节理组数;构造了两个新的相对力学参数,用 Matlab 进行多元回归分析,得出了这两个参数与最大节理面组数的公式及关系图。A discussion is initially made on the break mechanism and the generating condi- tions of the rock joints.Then,from the angle of engineering geology,a computation is made to calculate the rock joint groups on the basis of Mohr-Column theory.And two compara- tive parameters are constructed a regressing analysis is made with the help of Matlab soft- ware.Finally,a formula and plot of relations between the two parameters and the max of rock joints are drawn forth.
