Then consolidation tests under constant matric suction were performed through simulating graded confining pressures and overburden loading,and getting soil-water characters curve.

Some important factors which effect the characteristic curve of soil and water are analyzed herein and large amount of tests are conducted through which further knowledge of the said curve is obtained and proposals for reasonable applications of that curve to engineering are suggested.

Hysteresis model for soil-water characteristic curves;

Research on soil-water characteristic curve of unsaturated loess;

Experimental research on the soil-water characteristic curve of a landslide;

A study on effect of shear on soil-water characteristic curve of an unsaturated soil;

Laboratory experimental study of soil-water characteristic curves of unsaturated soils of Zhengzhou-Kaifeng underpass project

Experimental study of soil-water characteristic curve of remolded unsaturated clay

Laboratory tests on soil water characteristic curve of Qingjiangping landslide located in Three Gorges Reservoir are performed using four parallel-link unsaturated direct shear testing apparatus.

Based on the test,data of soil water characteristic curve,the estimation on a simplified supporting structure is made.

The permeability function equation formed with the parameters obtained from fitting the experimental results of soil water characteristic curve is found to be in coincidence with the actual measured results.

For four types of soils including sand,silt,clay and soft clay,the empirical relationship between matric suction and void ratio on drying path is established by utilizing the shrinkage curves and the soil-water characteristic curves which are determined through experimental tests.
