摘　　要：裂隙岩体坝基渗流分析成果是进行大坝工程设计的重要依据之一。采用非连续介质的裂隙网络渗流原理对裂隙岩体坝基进行渗流分析 ,计算工况包括设置灌浆帷幕和排水孔与否及其组合共四种情况。由计算结果可以看出 ,坝基总渗流量主要由灌浆帷幕的质量和帷幕区的渗透系数决定 ,坝基排水孔在排出渗水和降低渗透压力方面起到极其重要的作用。It is very important to investigate the seepage through dam foundation of fractured rock mass, which is one of the bases for design of dam construction. The principle of seepage through fracture network for discontinuous media is utilized to analyze the seepage through dam foundation with curtain grouting and drain holes in different combination. It can be illustrated from analysis results that the curtain grouting controls seepage discharge and the drain holes have obvious effect on drainage and pressure decreasing. [
