【摘要】 结合河北省某大面积吹填土地基处理工程,对真空动力固结在加固含饱和粉质黏土夹层的吹填土中的工艺参数进行了现场试验研究。通过对加固过程中超静孔隙水压力、深层沉降、强夯工艺参数等的分析研究,探讨了真空动力固结应用于含淤泥质粉质黏土夹层吹填砂土的加固机理。试验研究表明,真空动力固结处理吹填土地基取得了良好的加固效果,可为类似工程提供借鉴和指导。更多还原

【Abstract】 Combined with the foundation treatment of dredger fill in a project of Heibei province,the in-situ test on the large dredger fill foundation treatment with vacuum dynamic compaction method was completed.Through the analysis of the ultra-static pore water pressure,deep settlement and the technology parameters,mechanism applied to the of dredger fill with silty clay intercalation was discussed.The in-situ test indicates that foundation treatment with vacuum dynamic compaction method has achieved good foundation reinforce effects and all the test results can be referential to other similar projects.更多还原
