基于改进层次分析法的围岩分类模糊综合评价
首发时间:2008-09-18
摘要:本文运用改进的层次分析法和模糊数学综合评价相结合的办法对围岩进行分类。改进层次分析法解决了传统层次分析法中由评价指标所得的判断矩阵解的一致性问题、收敛速度及精度问题,最终得到各指标排序向量(即权重)与实际情况相符合。本文选取岩石质量指标(RQD)、湿抗压强度(Rw)、完整性系数(Kv)、结构面强度系数(Kf)、地下水渗流量(ω)这五项作为影响围岩分类的主要因素,运用改进层次分析法得到的各指标的权重符合工程实际,结合模糊数学方法对围岩进行分类,通过实例验证了该方法的科学性及可行性。

Fuzzy comprehensive evaluation based on improved analytic hierarchy process in surrounding rocks categorization
Abstract:This paper combines the method of Improved analytic hierarchy process with fuzzy comprehensive assessment, as a result ,we can use it to categorize surrounding rocks. IAHP can solve the problem of consistency、astringency and precision. Finally we got the reasonable weight. Chose five element which mainly affect the surrounding rocks categorization. An application example was given to verify the scientific nature and feasibility of the method in surrounding rocks categorization.
Keywords: improved analytic hierarchy process fuzzy comprehensive assessment surrounding rocks categorization
