摘要
The mechanical behaviour of discontinuous fractured rock masses significantly affects the displacements of rock engineers. In this paper, a damage mechanical theory is adopted to deal with some sets of joints distributed in rock masses. Based on the geometrical distribution of joints, a damage model which considers the influence of normal vector and area density of joints is used to describe the discontinuities. This damage model is programmed in finite difference software Flac3D, and an example of jointed rock masses is used to verify the validity of the model.
