Coupling meshless method and finite element method for seepage of jointed rock mass

The seepage analysis is important to many engineerings including seepage failure of the jointed rock mass, petrolic seepage in the jointed rock mass and waterproof design of the underground engineering. The analytical method can be restricted by some practice factors such as the non-homogenous and anisotropy of the seepage medium for the jointed rock mass, uncertain initial conditions, the boundary condition and the complex geometrical shape etc. The coupling meshless method and finite element method for the seepage of the jointed rockmass are developed in the paper. The seepage problems of the jointed rock mass are mainly solved by the meshless method. The discrete equations and relational computation formula of the method are derived by the variational principle. The boundary conditions are considered by the coupling method. At last, the validity and accuracy of the present coupling method solution are illustrated by two numerical examples.
