Abstract Aiming at the problems of subjective deviation, language ambiguity and incomplete information in the evaluation of green construction of tunnels in Karst area, a fuzzy comprehensive evaluation model for tunnel green construction was established based on extension analytic hierarchy process and grey system theory. The extension interval judgment matrix was used to deal with the subjective fuzziness of the index weight of green tunnel construction, the grey system theory was used to consider the index scores of multiple experts under the influence of incomplete information, and the comprehensive evaluation weight vector was obtained by combining the two, so as to improve the accuracy of the evaluation results.Through computer programming language Python development based on the model algorithm evaluation software, the software was applied to the green construction evaluation of the Dongqi Tunnel from Guilin to Liucheng Expressway, the evaluation results showed that the green construction grade of Dongqi Tunnel was good, and the performance of water pollution and material saving needed to be improved. The evaluation results were consistent with the actual situation of the Dongqi Tunnel construction site. The proposed model provided a new reference for the green construction evaluation of similar tunnels in Karst area.
