摘　　要：Darcy定律自从诞生以来已经被广泛地运用于多项工程技术领域。然而,越来越多的研究表明黏土介质地下水中存在着非达西渗流现象,而且这种现象不可忽略。本文综述了近几十年来黏土介质地下水非达西渗流的研究进展,重点概述了黏土介质地下水非达西渗流的存在性、非达西渗流的本构方程、非达西渗流的产生机理以及非达西渗流临界点转化判据等方面的研究成果,并对黏土介质地下水非达西渗流研究存在的问题进行了讨论,对今后的前沿研究方向进行了展望。Darcy＇s law has been widely used in engineering and technology field since its inception. Howev- er,more and more data show that the phenomenon of non-Darcy seepage has been found in clay media, which should not be ignored. According to the relevant data,this paper summarizes the development of non Darcy seepage in clay media over last decades, including four main contents= the existence of non-Darcy seepage in clay media,the constitutive equation of non-Darcy seepage,the mechanism of non Darcy seepage and the translation criteria for the appearance of non-Darcy seepage. The paper also discusses the problems of non-Darcy seepage in clay media and prospects the research directions in future.
