摘要 在以黏性土和中粗砂为主的素填土场地建设大型储罐,采用了强夯进行地基处理。针对夯后地基土分层不规律且传统分散式检测结果没有很好代表性等难题,采用模糊聚类方法对各检测点的土性指标和分布区域进行聚类归并,得到了在不同平面区域分布的场地土类别,为储罐基础的沉降趋势预测提供参考。通过比较实测的罐基础沉降数据与按模糊聚类方法得到的场地土类别,合理预测了罐基础沉降。 The soil improvement of dynamic compaction was used to construct large storage tank in plain-filled ground,which contain clay soil and medium coarse sand.Considering the problems such as irregular stratification of tamped foundation soil and the lack of representative results of traditional dispersion testing,in this paper,fuzzy clustering method to cluster and merge the soil property index and distributed area of each testing point was adopted,and obtained the soil types distributed in different plane region,which provided reference for the prediction of settlement trend of storage tank foundation.By comparing the measured tank foundation settlement data with the field soil category obtained by the fuzzy clustering method,the tank foundation settlement was reasonably predicted.
