Based on a tunnel project in Northeast China,according to the original data of the tunnel's rock structure acquired on the construction site,this article applied own developed GeoSMA-3D system,based on the theory of combining simple block models to build a complex one,and using discontinuous network diagrams to simulate virtual reality of rock mass geometry,a three-dimensional structure of structural plane of the rock surrounding was simulated,and a three-dimensional model of rock mass was established.Then,all blocks from structural plane division were obtained according to a method based on grid division.After that,a typical section from the model was selected and its data were imported into DDA code to analyze its stress and displacement in two-dimensional plane,and to make dynamic analysis of discontinuous deformation of tunnel surrounding rock,and the dynamic displacement map acquired has certain significance for advanced prediction and excavation and support of the tunnel.
