Consolidation Theory

The consolidation theory and test results of unsaturated soils were summarized in detail in this article, which include the recent development. And some existent difficulties and problems for consolidation theory of unsaturated soil were also summarized. The consolidation theory of unsaturated soils have well applicable future, but the theory is not mature and need the investigators’ further research.

As the complexity of unsaturated soil theory, and it must have a long test period when we study the unsaturated soils, so the conventional design analysis software does not provide such analysis, so we can imagine that such a slope stability analysis does not accurately reflect the actual state of the slope. Based on the known soil moisture content，this paper use the soil water characteristic curve and strength theory of unsaturated soil to calculate the strength reduction parameters of soil which can calculate the stability of the soil slope when using the common calculation method. It is noticeable that this method can be extended and applied if we establish regional databases for this simple method, and these databases can improve the accuracy of the calculation of slope stability.
