摘　　要：路堑边坡治理方案优选属不确定性的多属性决策问题。应用集对分析理论,探讨路堑边坡治理方案的多属性广义集对联系度决策模型,以待选方案分别与最优和最劣状态条件构建集对,以同一与对立表达式定量描述样本评价指标与最优、最劣指标值之间的联系度,计算待选方案与最优状态的相对隶属度,分析确定待选方案的优劣顺序。对比分析结果表明该模型有效可行,可为其他工程优选及不确定性问题的处理提供借鉴和参考。The optimization of treatment plans for cutting slopes is inherently uncertain and involves making decisions based on multiple variables. Using set pair analysis theory approach, here we discuss the uncertainties involved in this decision making, constructing set pairs between the most optimal and the most suboptimal plans and quantitatively describing connection degrees between an evaluation sample index and the best or worst conditions for each index under identical and opposite expressions. This enables the calculation of relative subordinate degrees between an untested plan and the most optimal conditions, an approach that allows the determination of the relative merits of any given untested plan. Comparative analysis results indicate that this method of decision-making during slope treatment is effective and practical, and also provides a reference for the optimization and calculation and treatment of uncertainties in other projects.
