CURRENT RESEARCH AND PROSPECTS IN MODELING SEEPAGE FIELD IN FRACTURED ROCK MASS

Fracture of rock mass is quite important and exists broadly in geotechnical engineering such as slope ,underground and foundation construction. It is got more and more regarded by engineers. The stability of slope and rock mass bearing capacity of building foundation are influenced by seepage in the mass. A variety of methods for analyzing seepage flow in fractured rock mass are introduced and discussed in brief. These analyses provide references for the selection of proper mathematical models to solve specific seepage flow in fractured rock masses. Some problems are put forward which need to be further investigated. The equivalent continuum model at present is widely used. However, the fractured rock mass geometry parameter and efficiency hole degree and coefficient of permeability are still awaiting to be examined furthermore. Micromechanics coupled with seepage model would have great theorical value.
