摘　　要：从基质吸力和水分特征曲线、非饱和渗透系数、非均匀流渗透机理、非饱和带中水气二相渗流四个方面评述了国内外有关非饱和渗透理论的研究成果,探讨了目前存在的问题和研究方向,并介绍了一种自研制的间接测量非饱和砂土基质吸力的方法.The relevant research results of unsaturated hydraulic theory at home and abroad are reviewed from four aspects,which are,matric suction and soil-water characteristic curve,unsaturated hydraulic conductivity,infiltration mechanism of non-uniform flow,and two phases（water and air）flow in unsaturated zone.The current problems and research directions are discussed,and a selfdeveloped method of indirect measurement of matrix suction of non-saturated sand is proposed.

关 键 词：非饱和渗透理论 基质吸力 水分特征曲线 渗透系数 指流
