| 摘 要： | 以湖南省湘潭——邵阳高速公路部分标段路基下伏岩溶勘量资料为基础，采用多级模糊评判理论与系统层次分析方法（AHP），建立了潭邵高速公路路基下伏岩溶稳定性的综合评判模型，并对其进行了二级模糊综合评判，其评判结果较准确地反映了这些标段岩溶的稳定程度。该工程实践也证明了此评判方法的可行性和可靠性，为高速公路岩溶区路基稳定性评价提供了可行的思路和方法，具有广泛的工程与学术价值。

| Abstract: | On the basis of the survey data of subgrade karst in part of sections in Xiangtan to Shaoyang Expressway in Hunan Province, multi class fuzzy evaluation theory and AHP are adopted. Model for comprehensive evaluation on stability of subgrade underlying karst in Tan Shao Expressway is established, and secondary fuzzy comprehensive evaluation made. The evaluation results precisely reflect the stability degree of the karst in these road sections. The project practice verifies the feasibility and reliability of this evaluation method, which provides a practical idea and method for evaluation of subgrade stability in expressway karst regions and has a wide engineering and academic values. |
