基于层次分析法的异形结构清水混凝土模板选型研究

Research on Formwork Selection of As-Cast Concrete with Special-Shaped Structure Based on Analytic Hierarchy Process

异形结构的复杂性以及清水混凝土的成型效果,对模板的选型提出了较高要求。本文通过专家评分法和层次分析法对异形结构清水混凝土模板选型做了详细研究,通过对国内外历年文献作研究综述,得出该目标层下准则层和方案层的各项因素,从而建立出该类模板选型的层次分析模型。最后以异形空间曲面清水混凝土跳水台为实例,基于层次分析法构建了跳水台模板选型的决策模型,进而对模型求解找出最优方案,为异形清水混凝土结构的模板选型提供了宝贵经验,同时也为异形结构清水混凝土构件的模板选型提供了一定的方法指导。

The complexity of special-shaped structure and the forming effect of fair-faced concrete put forward higher requirements for the selection of formwork.This paper makes a detailed study on the selection of special-shaped concrete formwork by expert scoring and analytic hierarchy process.Through reviewing the literatures at home and abroad,the factors of the criterion layer and scheme layer under the target layer are obtained,and the AHP model of this type of template selection is established.Finally,taking the special-shaped fair-faced concrete diving platform with curved surface as an example,the decision-making model of the diving platform formwork selection is constructed based on the analytic hierarchy process(AHP),and then the optimal solution of the model is found out,which provides valuable experience for the formwork selection of special-shaped fair-faced concrete structure,and also provides some method guidance for the formwork selection of special-shaped fair-faced concrete members.
