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.

The Stability

The study of unsaturated slope stability is one of issues in geotechnical engineering. Firstly, the different treatments of matric suction in the Sarma method are analyzed based on the Bishop’s unsaturated strength theory and Fredlund’s unsaturated strength theory respectively. Then, application of the developed method on the stability analyses of an unsaturated soil slope is also discussed. Through the comparison on the computational results, it still can be concluded that the computational error is slights, which analyzed by means of the developed Sarma method based on the Bishop’s unsaturated strength theory and Fredlund’s unsaturated strength theory.
