| Abstract: | In this paper,the concept,theory and model of FEM based on continuum seepage and fracture network technique based on non-continuum seepage are analyzed and compared,and calculation program of two methods is compiled,seepage example of dam foundation which is two dimensional steady,isotropic is compared and analyzed by two methods,thence their similarities and differences,advantages and disadvantages and applicability are summarized. |
