摘　　要：软弱土层的承载能力较低、稳定性差,难以满足建筑物承载能力和变形要求.地基处理是改善软弱土层承载能力、变形特性的重要工程技术措施.现阶段,软土地基处理的方法多样,各有优点及局限性,软基处理的影响因素也很多.如何选择合理的地基处理方案直接关系到工程质量、工程进度及工程投资.鉴于此,本文从技术性、经济性和环境性三个方面建立地基处理方案评价指标体系,以模糊层次分析法-粒子群算法为基础确定各指标权重,建立基于属性识别理论的地基处理方案的评价模型,并结合湛江某油库改扩建项目,证明该评价模型可以为地基处理方案比选提供可靠、合理的决策依据.The soft soil layer has low bearing capacity and poor stability,which is difficult to meet the requirements of building bearing capacity and deformation.Foundation treatment is an important engineering technical measure to improve the bearing capacity and deformation characteristics of soft soil layer.At present,there are many ways of soft foundation treatment,each with advantages and limitations,and many influencing factors of soft foundation treatment.How to choose a reasonable foundation treatment method is directly related to the quality,progress and investment of the project.In view of this,this paper establishes an evaluation index system of foundation treatment scheme from the three aspects of technology,economy and environment,determines the weight of each index based on fuzzy analytic hierarchy process-particle swarm optimization,and establishes an evaluation model of foundation treatment scheme based on attribute recognition theory.Combined with the reconstruction and expansion project of an oil storage in Zhanjiang,it is proved that the attribute evaluation model can provide a reliable and reasonable decision basis for the selection of foundation treatment schemes.
