A numerical study on the anisotropism behavior of infilled joint rockmass
The anisotropy of rock mass was mainly due to the conditions of the joints.In order to study the anisotropism behavior of infilled joint rockmass a mathematical model of the filling material was implemented to the two-dimensional distinct element code-UDEC using FISH language.The numerical analysis on anisotropy of the rockmass having one set of infilled joints was conducted.The results showed that the value of the cohesion of the filling material had a large influence on the test results.And the compressive stress of the sample changed a lot when the joints were infilled compared to nonfilled joints rockmass.With the increasing of the dip angle the compressive stress increased first and then decreased, and increase again at a certain dip angle.
