地下结构抗浮方案评价指标体系的建立

Building evaluation index system of schemes for anti-floating of the underground structures

通过对地下结构工程抗浮设计应用现状的分析,提出地下结构抗浮设计方案选择原则.在系统分析设计目标和影响因素的基础上,建立了地下结构抗浮设计方案优选的多级综合评价指标体系.应用模糊数学原理和方法分别对评价指标体系的各指标进行处理,建立了方案优选的多级模糊综合评价决策模型.通过工程实践中抗浮设计方案优选实例,阐述了方案优选的多级模糊综合评价的工程应用.

According to the analysis of the application actual state of anti-float design, the content and technical route are presented. Based on the systematically studies of the goal and influential factors of optimization of anti-floating scheme, multi-hierarchical comprehensive evaluation index system is proposed. Fuzzy mathematics is applied to study the evaluation index system and multi-hierarchical fuzzy comprehensive evaluation and decision model is proposed. With an example, the multi-hierarchical fuzzy comprehensive evaluation and decision model is introduced in detail.
