| Abstract: | 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. |
