The researches on seepage characteristic of fractured rock masses under the conditions of single fracture

hydraulic coupling

unsaturated seepage and considering the filled materials are reviewed and analyzed relatively. The results show that the experimental study played a very important role in researching on seepage characteristic of fractured rock masses; the more experiments that can simulate exactly the actual rock fracture should be done; the experiments considering the shear stress and 3-dimensional stress should be emphasized; the fully reasonable experiments of unsaturated flow in fractured rock masses are few now; the research on seepage characteristic of the filled fractured rock masses is more significant and should be strengthened. The available research directions are put forward for the future research on seepage characteristic of fractured rock masses.
