摘　　要：为解决当前山区高速公路选线过程中存在的影响因素多、参建各方侧重点不同、无法定量描述比选方案等难题,在充分调研中外高速公路及铁路选线影响因素的基础上,系统分析和总结中国山区高速公路选线影响因素,并将其概括为经济、技术、安全和环境4个方面,共计16个具体影响因子;依托西和—宕昌高速公路工程,组织项目区域所在地方政府、行业主管部门、业主、设计、施工、监理、第三方检测单位及科研院所相关专家共计164人组成专家组,采用层次分析法(analytic hierarchy process,AHP)对16个选线影响因子重要度进行评价。结果表明:环境指标中3个影响因素的综合权重平均分值较高,反映了工程建设领域环保意识的进一步加强。为进一步建立方案比选的优选模型,以依托项目灯塔—蒿林村段路线的方案比选为例,在AHP的基础上运用逼近理想解的排序法(technique for order preference by similarity to idea solution,TOPSIS)对比选方案进行优选,4种比选方案的优越度分别为2.84、0.56、0.72、2.15,即方案1最优。研究成果在全面分析山区高速公路选线影响因素的前提下,采用AHP-TOPSIS综合评判指标体系模型,在充分利用专家经验的同时,又能客观、科学的对比选方案进行最优解排序,较好地解决了山区高速公路选线问题,可为类似线形工程方案的选择提供参考。In order to solve the problems of multiple influencing factors,different focuses of participating parties,and inability to quantitatively describe the comparison and selection schemes in the current process of selecting routes for mountainous expressways,based on thorough research on the influencing factors of expressway and railway route selection at home and abroad,the influencing factors of expressway route selection in mountainous areas of China were systematically analyzed and summarized,and four aspects:economy,technology,safety and environment were summarized,totaling 16 specific influencing factors.Based on the Xihe to Tanchang Expressway project,a group of 164 experts from the local government,industry regulatory departments,owners,design,construction,supervision,third-party testing units,and research institutes in the project area were organized to form an expert group.The analytic hierarchy process(AHP)was used to evaluate the importance of 16 route selection influencing factors.The results show that the comprehensive weight average score of the three influencing factors in the environmental indicators is high,reflecting the further strengthening of environmental awareness in the field of engineering construction.To further establish a optimization model for scheme comparison,taking the scheme comparison of the route from the project Dengta Village to Haolin Village as an example,the technique for order preference by similarity to idea solution(TOPSIS)method based on the AHP was used to compare and select schemes.The superiority of the four comparison schemes is 2.84,0.56,0.72,and 2.15,respectively,indicating that scheme 1 is optimal.Based on a comprehensive analysis of the factors affecting the selection of mountainous expressway routes,the research results adopt the AHP-TOPSIS comprehensive evaluation index system model.While fully utilizing expert experience,it can objectively and scientifically compare the selection schemes for optimal solution ranking,effectively solving the problem of mountainous
