摘　　要：充分利用大量公路黄土路堑高边坡实例,构建了基于范例推理的边坡稳定性预测模型。该模型是将已建黄土路堑高边坡实例作为源范例,而将待分析边坡作为目标范例,通过源范例和边坡范例之间的相似度计算,得到目标范例与源范例之间的相似性序列,找出与目标边坡范例最相似的源范例,从而实现了黄土路堑高边坡的稳定性预测。实例分析表明,该法不仅原理简单、使用方便,而且效果良好。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.
