Abstract
The soil water characteristic curve is an important hydraulic characteristic parameter of unsaturated soil, and plays an important role in the analysis of unsaturated soil strength and slope stability. At present, there are few studies on soil water characteristics in Xining area. In this paper, the matrix suction value of undisturbed loess in Xining area is tested by filter paper method under different water content, then the soil water characteristic curve is obtained. The specific analysis of the test results shows that the soil sample at the same depth increases the matrix suction during the dehydration process, and the volumetric water content of the soil sample decreases gradually. This paper lays a foundation for the study of the impact of rainfall infiltration on the shear strength of slope soil and the stability impact.
