黏性填土地基处理监测实践及强度增长规律研究

Research on Monitoring Practice and Law of Strength Growth of Cohesive Fill Foundation Treatment

某港区堆场表层为回填形成的黏性填土,采用高真空击密法进行地基处理,通过对高真空击密施工过程中的夯坑沉降、土体位移、地下水位、孔隙水压力的观测以及不同阶段静力触探检测数据的分析,确定了黏性填土在地基加固过程中的强度增长规律,也为高真空击密法在同类型的场地地基处理中的应用提供宝贵资料。

The surface layer of the stockyard at a harbor is filled with adhesive soil,and high vacuum compaction method has selected in foundation treatment.By observing the ramming pit settlement,soil displacement,underground water level,pore water pressure during the construction of high vacuum compaction,and analyzing CPT data at different stages,the law of strength growth of filled adhesive soil in the process of foundation reinforcement were determined.The research results are valuable to the application of high vacuum compaction method in similar foundation treatment.
