| 摘 要： | 结合上海某工程大面积吹填土地基处理,对真空动力固结在加固含饱和软粘土夹层的吹填土中的适宜性和相应的工艺参数进行了现场试验研究。通过对加固过程中地下水位、超孔隙水压力、工艺参数等的分析研究,探讨了真空动力固结应用于含饱和软粘土夹层地基处理时的加固机理。研究结果表明,真空动力固结方法用于加固含饱和软粘土夹层的吹填土地基有较好的适用性。

| Abstract: | Combined with the foundation treatment of dredger fill in an engineering of Shanghai,the in-situ test on the large-area dredger fill roadbed treatment with vacuum dynamic compaction method was finished.Through the analysis of the variation of underwater level,pore pressure and the technology parameters,the mechanism on this new method applied to the dredger fill with soft clay intercalation was discussed.All the results confirm the viability of the vacuum dynamic compaction method to strengthen large area grounds with hydraulic fills with soft clay intercalation. |
