基于EAHP-GST的岩溶地区隧道绿色建造模糊评价

Fuzzy evaluation model based on EAHP-GST for green construction of tunnel in Karst area

针对岩溶地区隧道绿色建造评价中存在的主观偏差、语句模糊和信息不全等问题,建立了基于可拓层次分析法-灰色系统理论的岩溶地区隧道绿色建造模糊综合评价模型。采用可拓区间判断矩阵处理隧道绿色建造指标权重取值存在的主观模糊性问题,利用灰色系统理论考虑多位专家在信息不全影响下的指标评分,并将两者结合获得综合评价权向量,以提高评分结果的准确性。通过计算机编程语言Python开发基于该模型算法的评价软件,将软件应用于桂林至柳城高速公路东起隧道绿色建造评价。评价结果表明:东起隧道绿色建造等级为良,且水污染和节材方面有待提高,与施工现场的实际情况相符。该模型的提出为岩溶地区类似隧道的绿色建造评价提供了新的参考。

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.
