| Abstract: | 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. |

| Keywords: | unsaturated hydraulic theory matric suction characteristic curve of soil-water filtration coefficient finger flow |
