Abstract


In rock engineering problems , the application of the boundary element method is more extensive. But most of the applications are based on isotropic rock mass , although it relates to anisotropic rock JOINTED damaged rock is still relatively small . On the basis of previous work on the boundary element method JOINTED damaged rock to do a more in-depth study . Boundary element program developed several sets for different rock mass . The main work is as follows : 1 , the boundary element method in anisotropic rock , prepared on the basis of the isotropic twofs program anisotropic the Asio-twofs Procedure . Were calculated whether or joints in the rock mass rock engineering fault analysis jointed fault of the cavern . 2 , the introduction of multi - fractured rock mass constitutive model under compressive stress to the boundary element method , boundary value problems in anisotropic multi- fractured rock mass and in the anisotropic the Asio-twofs program on the basis of preparation of the the corresponding anisotropic fractured the Cra-twofs procedure . Of rock fracture cavern . 3 , the introduction of two-dimensional anisotropic damage constitutive model of the boundary element method , anisotropic boundary value problem of damaged rock , and the preparation of the corresponding in the anisotropic the Asio-twofs program on the basis of each anisotropic damage the Dam-twofs program. The rock mass damage cavern . 4 , the boundary element method in inhomogeneous rock . In the Asio-twofs program prepared for analysis and calculation of anisotropic rock band lining the cavern the Liner-twofs procedures . Lining cavern excavation . , Respectively, with the lining of the rock mass anisotropy in fractured rock , and anisotropy of damaged rock engineering problems .
