摘　　要：在大面积吹填地基处理过程中,软土地基稳定性是工程安全的关键影响因素,因此在吹填逐步加载及加载完成预压阶段对地基稳定性的判断至关重要。而影响地基稳定性的因素不仅具有随机性,也具有模糊性。选取一些对地基稳定性具有显著影响的因素,建立层次结构模型,确定了评价指标的权重矩阵,并利用模糊综合评价方法构建了地基稳定性的分级模型。将此模型应用于一项吹填处理工程,对软土地基在吹填过程中的稳定性进行模糊综合评价,评价结果与现场实际基本吻合。The stability of soft soil foundation is the key factor of engineering safety in the process of foundation treatment of large area blow fill,so it is very important to evaluate the stability of foundation in the phase of blow fill loading and the preloading stage after loading.The factors that affect the stability of the foundation are not only random,but also fuzzy.Select some factors that have significant influence on the stability of the foundation,establish the hierarchical structure model,determine the weight matrix of the evaluation index,and use the fuzzy comprehensive evaluation method to construct the classification model of the stability of the foundation.This model is applied to a blow fill treatment project to evaluate the stability of soft soil foundation in the process of blow fill,and the evaluation results are basically consistent with the field practice.
