摘    要:提出基于模糊相似优先的边坡稳定性评价范例推理方法。运用模糊相似优先的概念,构造了一个基于模糊相似优先的边破范例检索模型。以每一个边坡稳定性的影响因素,分别建立了边坡的目标范例与源范例这间的模糊相似优先关系。经过影响之间的两两比较,获得了不同的影响因素下边坡的目标范例与源范例之间的相似性序列,在确定影响因素各自的权重分配之后,计算得到边坡的目标范例与源范例之间的综合相似性序列,从而最终找出与边坡的目标范例最相似的边坡的源范例。在以往的边坡范例与前的边坡稳定性评价之间,建立了合理的推理关系,实现了坡的稳定性评价。实例分析表明:边坡的稳定性评价结果与边坡的实际状态完全一致。

关 键 词:范例推理  模糊相似优先  边坡  稳定性  评价

Abstract:A case-based reasoning approach to slope stability evaluation based on fuzzy analogy preferred ratio is presented,and a relative slope base case indexing model is set up. In this model,the fuzzy analogy preferred relationship between slope target case and slope base case is determined,and the similar series between the two cases with different affecting factor on slope stability is given. Determining the factor weights,the comprehensive similar series between the two cases is 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 case is evaluated. It is shown from examples that the result of stability evaluation of the slope is the same as the practical state,and the approach is simple,visual,practical,and convenient to use.
Keywords:case-based reasoning  fuzzy preferred ratio  slope  stability evaluation
