摘　　要：文章基于对岩溶路基稳定性影响因素的分析,以娄新高速公路工程为例,借助二级模糊评判理论,建立了岩溶区路基稳定性二级评判模型,探讨了模糊关系R及权值确定方法,并将该方法用于娄新高速公路K30+935~K31+345段岩溶路基的稳定性评判。应用结果说明二级模糊评判理论可以用于岩溶区路基稳定性评判,具有广泛的工程应用价值及学术研究意义。Based on analyzing the factors affecting the stability of karst roadbed,with Lou^n Expressway project as the example, and via to secondary fuzzy evaluation theory, this article established the sec-ondary stability evaluation model for roadbed in karst area,discussed the fuzzy relation R and weights determination method,and used this method in the stability evaluation for the karst roadbed of K30＋ 935- K31＋ 345 section in LouxJn Expressway.The application results indicated that the secondary fuzzy evaluation theory can be used for the roadbed stability evaluation in karst area, with the broad engi- neering application values and academic research significance.
