AbstractA new interface model for discrete element method, named structure layer model, is introduced. Structure layer is composed of spring elements and adopted to continuumdiscontinuum element method, CDEM. It is with thickness but without mass. Thin intercalation in the discontinuous geologic bodies as well as the interface between elements in the continuous problem can be modeled by structure layer. Different from the traditional interface spring model in discrete element method, the stiffness of structure layer has definite physical meaning, because the layer is with real thickness and all the parameters are determined by the factual material. Not only tension and shear, but also Poisson effect and pure shearing can be expressed with structure layer model, which increases the accuracy of numerical modeling for thin structure layer. Meanwhile, since there is no need to set large spring stiffness to ensure displacement continuity of nodes at the same place as in the interface spring model, large time step can be adopted, efficiency of computation is increased.
