The Case Study Analysis of Strain–Stress for Jointed Rock Mass Using Element Free Galerkin Method and Paton’s Failure

In this paper the application of mesh-free (Element Free Galerkin) method in analyzing the nonlinear and elastic-plastic behavior of jointed rock mass is presented. The domain is represented by a set of arbitrary distributed nodes and the essential boundary conditions are enforced using penalty method. The Patton's failure criterion was used for behavior of joint failure. Few examples, showing the effectiveness of the method in predicting the elastic-plastic behavior of jointed rocks are presented and the results are compared well with finite difference method.

Good Agreement

Referring to the previous shearing model tests on intermittence jointed rock mass, DDARF method was adopted to conduct the corresponding numerical simulation. It could be concluded from the cracking failure phenomena that the results of the numerical simulation and the tests were in good agreement. Then the intermittence joints were arranged as en echelon and different cracking failure phenomena, peak shear strengths and strain-stress relationships were also obtained.
