SCI HOEK BROWN FLAC3D SERIES
In order to develop the numerical program for JRC. By employing the longwall mining method, a series of intensive strata structure responses and activities will be induced including stress redistribution, fracture extension and strata movement. The JRC/JCS model is the nonlinear failure criterion and generally believed to describe the characteristics of joints better than other models. In practice, the intermediate principal stress has certain influences on the strength of geomaterials (e.g., rock and soil) or concrete. (2002) Hoek-Brown failure criterion, 2002 edition, in Proceedings 5th North American Rock Mechanics Symposium and 17th Tunnelling Association of Canada Conference, R. The joint surface is widely distributed in the rock, thus leading to the nonlinear characteristics of rock mass strength and limiting the effectiveness of the linear model in reflecting characteristics. The evaluation of the bearing capacity of footings usually does not take into account the effect of the intermediate principal stress.
