FORECAST MODEL OF STABILITY OF HIGHWAY LOESS CUTTING-SLOPES BASED ON CASE-BASED REASONING

By utilizing lots of highway loess cutting slopes mostly, this paper presents a forecast model of slope stability based on case-based reasoning. Slope examples are taken as slope base cases. Slopes that will study are taken as slope target cases in the model. Through calculating the similarity between slope base cases and slope target cases, the similar series are determined, and the most similar base case to the slope target case in the base cases of slope is found out. Finally,the slope stability of target cases is evaluated. It is shown from examples that the result of stability forecast of the slope is the same as the practical state, and the approach is simple and convenient to use.
