| 摘 要： | 针对现行隧道围岩分类中存在的"模糊性"问题,引进模糊层次分析模型,实现了围岩定性分类向定量分类的转变,经过工程实践取得了良好的效果.首先确定了影响隧道围岩质量的主要因素,如岩块坚硬程度、结构面发育程度、岩石质量指标以及地下水出水特征,然后建立了模糊评价模型,并采用层次分析法确定了各因素的权重,最后针对堡镇铁路隧道围岩采用模糊层次综合评价决策的数学模型所得到的结果对隧道各段岩体质量的级别进行了划分.

| Abstract: | Aimed at the fuzzy question in wall-rock classification,Fuzzy-AHP analysis model is established to realize the transformation from qualitative classification to quantitative classification.The model is established after the major factors influencing tunnel wall-rock quality are determined,such as the rock blook hardness,the structural plane's development,the rock quality designation and groundwater.Fuzzy-AHP arrangement is analysed in order to establish the weight value of each influencing factor.Finally,th... |
