| Abstract: | In accordence with the structural characteristics and the mechanical beha- vior of rock mass with intermittent joints,this paper discuses a number of the problems in the analysis of crack strength of the rock mass by means of the method of finite element,and at the same time,presents the correspo- ding processing method and program of finite element. Based on the resuts of numerical analysis for gypsum model with a group of intermittent joints using the program,the properties of compressive shear strength of this class of rock mass is also provad in the paper. |
