基于集对分析同一度的基坑支护方案综合评价

Comprehensive evaluation of supporting schemes for foundation pits based on identical degree of set pair analysis

摘要: 针对基坑支护方案综合评价中各指标的不相容性,利用集对分析方法,将评价基坑支护方案的多个指标合成为一个与最优评价集的相对贴近度,用来描述基坑支护方案的综合效益。以可供选择的4种支护方案为例进行了评价,得到综合效益最优的方案。

Abstract: By use of the set pair analysis and considering the incompatibility of indexes for the comprehensive evaluation of supporting schemes of foundation pits,indexes for the evaluation of supporting schemes were combined to be a relative closeness degree of optimal evaluation sets to describe the comprehensive benefit of supporting schemes.Four optional supporting schemes were chosen for the evaluation,and the optimal comprehensive scheme was obtained.
