【Abstract】 In this paper,according to the structural features of rock masses,a meshless model for jointed rock masses is constructed.This model is prior to other one.Meshless only need nodal data,not element one.The interpolants are polynomials which are fit to the nodal by moving least squares approximation in the domain.In this model,a jointed rock masses is regarded as a system of relatively intact rock blocks connected by joints or planes of discontinuity.This method avoids dividing the mesh.Furthermore,the discontinuities of rock masses are also taken into consideration. A?2D meshes program is established and a simple example is given.The results showed that the models are reasonable and feasible.更多还原
