Three soil profiles were selected from the Ejin Oasis in the lower reaches of the Heihe River in northwest China to collect soil samples at different depths and groundwater samples for determination of chemical compositions of the samples, and to measure the changes in soil moisture potentials at different depths of the profiles.

The method introduced soil-water potential (SWP) equation and moving mesh FEM into the governing equations of traditional Biot s consolidation theory.

This paper analyzes two conditions required by vacuum preloading improving the soft soils,and explains the seepage mechanism during the course of improvement with the soil-water potential principle,the conversion from pore-water pressure to effective stress is illustrated,which demonstrates the incremental effective stress is consisted of difference of atmospheric and hydraulic pressure.

The conception of soil water potential was used for the analysis and explanation of driving force and form of water migr.

To serve for engineering, ground water level in vacuum preloading is defined on the basis of conception of soil water potential.

The results showed that the saline-alkaline soil water potential Absolute value will be increased with the content of soil liquid decrease;the same kind soil of water potential Absolute value will be increased with the mcrease of concentration of soil liquid.
