摘　　要：为解决兰州南绕城项目垃圾场处治的技术难题,基于模糊数学、层次分析法和逼近理想解排序法的基础上,建立了综合评判指标体系模型,对翻挖填筑、桥梁、孔内强夯和预应力管桩4种拟选方案进行方案决策。以经济、技术、可靠度为评判指标,通过层次分析法确定其权重向量,利用逼近理想解排序法对结果进行优先级排序,最终确定拟选方案的综合优越度。结果表明:4种拟选处治方案的优越度分别为0.785、1.536、1.327、2.560,即第四种处治方案(高强预应力管桩方案)最优,为垃圾场处治方案的优选及类似工程的建设者提供科学依据。To address the technical challenges of the landfill treatment project in Lanzhou south ring road project,a comprehensive evaluation index system model was established based on fuzzy mathematics,analytic hierarchy process,and technique for order preference by similarity to ideal solution.This model facilitated decision-making among four proposed treatments:excavation and filling,bridge construction,dynamic compaction in boreholes,and prestressed pipe piles.The criteria for evaluation included economic,technical aspects,and reliability.The weight vectors were determined using analytic hierarchy process,and the prioritization of the options was conducted through technique for order preference by similarity to ideal solution.The results revealed the comprehensive superiority of each option as follows:0.785,1.536,1.327,and 2.560respectively.The fourth option,involving high-strength prestressed pipe piles,emerged as the most optimal.This provides a scientific basis for selecting landfill treatment schemes and offers guidance for similar construction projects.
