AN APPLICATION OF GENERALIZED DOUBLE POROSITY MEDIA MODEL FOR COUPLED STRESS AND GROUNDWATER FLOW ANALYSIS IN FRACTURED ROCK MASS

By analysis of test data on stress and seepage in rock mass, a fractal geometry formula for relation between stress and seepage is presented in the paper. According to the formula of relation between stress and seepage, a generalized double porosity media model for coupled seepage and stress field in fractured rock mass system is set up. The model is based on rock mass structure in the study area) which is considered as generalized double porosity media. It is shown that the model is satisfied with practice application to seepage and its control in some hydroelectric engineering projects and stability evalution of high slope rock.
