Optimal Selection of Highway Crossing Waste Site Foundation Scheme Based on FUZZY-APH-TOPSIS
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 a-mong 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 vec-tors 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 2.560 respectively.The fourth option,involving high-strength pres-tressed pipe piles,emerged as the most optimal.This provides a scientific basis for selecting landfill treatment schemes and offers guidance for similar construction projects.
