基于主成分分析法的深基坑支护方案优选模型

摘要

深基坑支护方案受多种因素影响,而且因素之间可能存在重叠、相关关系.为选择经济合理、整体综合指标最优的支护方案,在分析影响深基坑支护体系因素的基础上,将主成分分析法应用于支护方案优选中,提出基于主成分分析法的深基坑支护方案优选模型.并成功应用于深基坑工程支护体系综合决策中,为复杂系统的综合决策提供了一条新途径.%The plan of deep foundation pit supporting is influenced by many factors, and overlap or relationship may exist among factors. For choosing reasonable,overall comprehensive index support solutions,on this paper,principal component analysis be applied to optimize bracing projects founding on the analysis of the influence factors of deep foundation pit bracing system and successfully make decision on the deep foundation pit engineering support system,which offers a new approach for complex system of the comprehensive decisionmaking.
