Comment on the Models of Seepage Flow in Fractured Rock Masses

In this paper,various models for analysis of seepage flow in fractured rock masses are systematically summarized and studied.Bases on the seepage mechanism,the merits、demerits and applied conditions of these models are illuminated.In addition,their application circum stance in engineering is stated.Above all,the continuum-discrete coupled model which takes advantages of both equivalent continuumm odel and discrete fracture model has the most vast vistas for engineering applications.
