Abstract: With the rapid infrastructure development in China, there are more and more high and steep man-made slopes, so we have higher requirements to develop for accurate and real-time slope stability analysis methods. In recent years, slope stability analysis method based on reliability theory has been greatly developed. This paper briefly reviews the development of slope reliability analysis theory, and summarizes the important research advances and latest achievements in this aspect. The features of several commonly used methods are described and compared in detail. On this basis, some comments and suggestions are given to the research weakness and future development trends in slope reliability analysis theory.
