摘　　要：根据国内某碾压混凝土工程坝体芯样渗透特性试验成果,对碾压混凝土渗透特性规律进行了总结评述。认为在持续水头作用下,碾压混凝土的渗透具有时效自密性;高水头作用下的碾压混凝土可能存在偏达西流现象。Based on the results of percolation test for core samples from a certain roller compact concrete dam in China, this paper presents a summary review on the law of precolation features of roller compact concrete. It concludes that percolation of roller compact concrete is of self - compactness by time effect under continuous action of water head and there may exist partial Darcy flow regime in roller compact concrete under high water head.

关 键 词：碾压混凝土 渗透试验 时效自密性 达西流
