摘　　要：面板坝的渗漏量是面板坝运行性态的综合反映,渗漏量评判是涉及工程安全的重要问题。对国内外1971~2009年完建、坝高为78~233 m的37座面板坝按面板面积均化渗漏量进行工程类比后,大致拟定出以下判据:面板均化渗漏量在12 L/(s·万m^2)以内时,表明渗漏量小;在12~24 L/(s·万m^2)之间时,表明渗漏量较小;大于24 L/(s·万m^2)时,表明渗漏量偏大。这些从代表性面板坝工程实际运行状态统计分析得出的判据,可供类似面板坝工程渗漏评判时参考。The leakage is a comprehensive reflection of face rockfill dam operation state, and leakageevaluation is an important issue related to engineering safety. For 37 domestic and abroad face rockfilldams completed during 1971~2009, more than 78 m in height, engineering analogy of leakage was con-ducted by homogenizing the face area. The criteria could be roughly drew up as follow： the face averageleakage within 12×10- 4L/（s·m2） indicates a small amount of leakage;（12~24）×10- 4L/（s·m2） indicatesmoderate amount of leakage; and more than 24×10-4L/（s·m2） indicates that the amount of leakage is toolarge. The statistical criterion could be a reference for similar dams.
