The Application Of The Fuzzy Clustering Interactive Theory In The Slope Stability Analysis

Landslide frequently occurs in China that threatens the people's life and property and economic construction greatly. With the rapid development of our modern construction, more and more high-steep and deep slopes appear in many engineering fields such as hydroelectricity, mine, harbor, road, railway and energy, etc. Therefore, how to analyze and evaluate slope stability reliably and effectively is very significant to slope safety and landslide forecast in theory and practice. This paper reviews the development trend of various analytical methods and brings forward the research object and content.The indeterminacy in the slope stability analysis is due to the heterogeneity and complexity of the rock. Moreover the fuzzy of rock has profound and universal significance. The paper uses the "the indeterminate method" the fuzzy theory to solve "the indeterminate issue". And the method is one of new attempts to analyze the slope stability.The indeterminacy in the slope stability analysis is illuminated by the geological models, mechanical parameters and slope failures at the initial stage of the paper. And the significant of the fuzzy theory in the practical application is also stated in the beginning of the paper. Then the fuzzy clustering interactive theory, with the engineering background of the slopes of the Lingbo mines, is used to analyze the slope stability, based on the rock mechanics tests. And the numerical simulation method, which is widely used in analyzing slope stability, is utilized to compare with the fuzzy clustering interactive method. And the results show that the fuzzy clustering interactive theory can be applied to predict the slope stability and has good qualities in some aspects. Lastly, the whole paper is summarized, and some promising problems are discussed.
