Slope Stability Evaluation by the Improved AHP and Extenics Theory

Abstract:

According to the improved 3 scales (0, 1, 2) Analytic Hierarchy Process (E-AHP) and Extenics theory, an evaluation model is built to evaluate the slope stability. The model takes into account nine indexes that affect the slope stability. The classical matter element and extensional matter elemen are established by collectting actural data. And combined with the specific example, this model accurately calculated the stability state of the slope. The results shown that it not only can take advantage of Extenics Matter-Element theory and the correlation function to study the relationship between index and slope stability, but also can avoid the shortcomings of the traditional AHP judgment matrix inconsistent. It is a new model to evaluate the slope stability.
