摘　　要：论文对基于连续介质渗流理论的有限单元法和非连续介质渗流理论的裂隙网络法的概念、理论和模型进行分析和比较,编制了两种数值方法的计算程序,并利用两种方法对二维稳定、各向同性坝基渗流算例进行分析对比,从而总结出两种方法的异同,优缺点及其适用性。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.
