摘要
桩基础种类和施工方法多样,不同工况下如何选取最优方案是个难题。为较好解决这一问题,建立了一种新的基于层次分析法(AHP)的桩基设计方案模糊层次结构优选模型。首先,分析和确定了影响桩基方案决策的因素,构建了评价桩基方案优劣的指标体系;然后,运用层次分析法确定评价指标的权重;最后,利用模糊数学建立了多目标的决策模型,从而评选出最理想的桩基方案。将该模型应用于实际工程中,取得了较好的效果。
There are various types and construction methods of pile foundation, and how to choose the optimal scheme under different working conditions is a difficult problem. In order to solve this problem, a new AHP（Fuzzy AHP） optimization model for pile foundation design is established. Firstly, the factors influencing the decision-making of the pile foundation are analyzed and determined, and the evaluation index system is established. Then, the weight of the evaluation index is determined by the Analytic Hierarchy Process（AHP）.Finally, a multi-objective decision-making model is established by fuzzy mathematics, So as to select the best pile foundation scheme. The model is applied to practical engineering, and achieved good results.
