高能级强夯法处理非均匀回填地基试验研究

摘要

对广东某石化厂油罐非均匀回填土地基进行高能级强夯试验,试验结果表明,强夯有效加固深度达12.5m,影响深度达14m,地基承载力特征值和变形模量均有大幅提高,满足设计要求,为类似工程提供借鉴经验.%In this paper, experiment of 10000kN·m Dynamic Compaction (DC) was successfully put in practice on a rubble fills site in coastal area. The experiment provided the parameters for the design, construction and detection of 10000kN·m DC. It is suggested that the Effective Depth of Improvement (EDI) reaches 12. 5m for gravel and sand, and the influential depth reaches 14m, if used in the table 6. 2. 1 of the Ground Treatment Code of China.
