Equivalent Continuum Model and its Application to the Seepage Analysis of Rock Slope

During the analysis on the seepage field of fractured rock mass by using the equivalent continuum model, the coefficients of permeability obtained from the pump-in test and the field survey of rock mass structural faces are compared synthetically. Then the modified permeability tensor that can reflect the intrinsic geological environment elements is proposed. Finally, the method is applied to the seepage analysis of open-pit slope fractured rock mass successfully.
