＜正＞The equivalent cotinuum model to be applied to asertain the constitutive of two or three dimensional problem in rock is presented in this *** the model,the rock cut by joints is treated as anisotropic material, the discontinuity of rock and irregularity of joint intermission are also can be simulated.A multi-lamina model is used to analyses rock mass strength. The rock’s mechanical properties and stress distribution is take into accont.

This paper compares numerical modeling of the effect of stress on solute transport （advection and matrix diffusion） in fractured rocks in which fracture apertures are correlated with fracture lengths. It is mainly motivated by the performance and safety assessments of underground radioactive waste repositories. Five research teams used different approaches to model stress/deformation, flow and transport pro- cesses, based on either discrete fracture network or equivalent continuum models. The simulation results derived by various teams generally demonstrated that rock stresses could significantly influence solute transport processes through stress-induced changes in fracture apertures and associated changes in per- meability. Reasonably good agreement was achieved regarding advection and matrix diffusion given the same fracture network, while some observed discrepancies could be explained by different mechanical or transport modeling approaches.
