摘要
针对现有边坡治理方案评价方法所存在的缺陷与不足,同时考虑到评价过程中的多层次、多目标、模糊性、全面性等特征给决策过程所带来的困难,基于区间模糊分析理论,构造了边坡治理方案的多层次综合评价模型。工程实例计算表明:该模型体现了边坡治理方案各影响因素与评价指标的逻辑关系,反映了决策过程中的层次性和全面性;区间数的引入可以很好的体现参数取值不确定性、模糊性的特点;权向量能衡量不同指标间的相对重要程度,充分体现了主要因素的影响,同时也兼顾了次要因素的作用,使边坡治理方案决策过程更加合理。为边坡治理方案决策提供了一种合理可行的方法。
Aimed at the shortcomings of decision-making method for slop treatment scheme and considering the multi-objective, multi-level, vagueness and comprehensiveness in decision-making process, a multi-level comprehensive evaluation model for slope treatment scheme was established based on the theory of interval fuzzy analysis. Engineering examples show that the model reflects the logical relationship between the factors and evaluation indexes of the slope treatment scheme, reflects the levels and comprehensiveness of decision-making process. The interval numbers can well reflect the characteristics of decision-making process in the parameter values. Weight vectors can measure relative importance between different indexes and fully reflect both the influences of main factors and the effect of secondary factors. This model makes slope treatment scheme a more rational decision-making process and provides a reasonable and feasible method for slope treatment scheme decision-making. 2 tabs, 1 fig, 11 refs.
