摘要
桩型选择是桩基设计中首先要面对的问题。传统的方法多采用"主要因素法",即在影响桩型方案选择的各种因素中选择最主要的而又可以量化的几项指标来进行比较。文章应用模糊综合评判法和层次分析法(AHP)相结合的理论对桩基的选型方案作定量分析,选择最优桩型。同时将此方法应用于福州地区的工程实际,综合分析了桩型选择的三个影响因素:持力层、层数和环境影响。分析的结果与实际工程相符,验证了该方法在桩型优化选择方面的有效性。
An evaluation approach combining fuzzy synthetic evaluation method with AHP （ Analytic Hierarchy Process ） is employed to evaluate the optimizing selection of pile type in this paper. The proposed method is applied to the engineering practice in Fuzhou area. Three influential factors, bearing strata, numbers of building stories and environment, are considered in the ease history. The analytical results show that the selection based on the proposed theory agrees well with the engineering practice.
