基于AHP分析的二级模糊综合评价模型及在边坡风险易损性评价中的应用

Study of AHP fuzzy method and its application evaluating of damageability in slope

边坡工程分析中的易损性分析包含数量众多、逻辑关系复杂的影响因素,并且其中很多因素的评价具有模糊性。AHP分析能把定量分析和定性分析结合起来,并反映出各因素之间的层次性;模糊分析能反映各因素模糊信息。本文将二者相结合,建立了基于基于AHP分析的二级模糊综合评价模型,以某危险边坡的易损性评价为例,介绍了该方法的应用。

The vulnerability analysis for slope engineering includes lots of complicated factors, and some of these factors have fuzziness. AHP analysis can combine quantitative analysis with qualitative analysis, and reflect these factors＇ hierarchy. Fuzzy analysis can reflect these factors＇ qualitative information. In order to combine AHP analysis with fuzzy analysis, two level fuzzy comprehensive evaluation models were built based on AHP. At last, the method was applied to the vulnerability evaluation of a critical slope, and its application was discussed in detail.
