Abstract: In order to probe into the approaches and effects of reducing the water content in saturated over-wet soils in moist and rainy areas, the water drainage effects of the vacuum preloading method and electro-osmosis method were compared via indoor model tests. The result indicates that the both methods can effectively reduce water contents in saturated over-wet soils and obtain the desired effects of drainage and consolidation, but there exists inhomogeneity in the spatial distribution of water-reducing content when they are used. When the vacuum preloading method is adopted, water contents in top and bottom soil layers do not change significantly, and consolidation effect is relatively homogenous.
