摘　　要：江苏沿海某电厂对场地饱和粉砂吹填土进行了多种浅地基处理试验,文章选择了其中的高真空击密法浅地基处理试验方法,通过对试验过程中场地的沉降和超孔隙水压力的监测成果,以及试验结束后吹填土复合地基的标准贯入试验、静力触探试验和静载荷试验处理效果检测成果的分析,研究了高真空击密应用于饱和粉砂吹填土地基处理时的加固机理,对高真空击密加固饱和粉砂吹填土地基的研究得出了一些有益的结论,为在类似场地中的应用提供了依据.Based on the foundation treatment used in a dredger filled with silt electric power plant in Jiangsu province,the field experiment result are used to check the effect of the foundation treatment of high vacuum drubbing.Through analyzing the monitoing data such as the settlement of the treatment ground and the excess pore water pressure and the result of standard penetration test and static cone penetration and plate load test,the mechanism of the HVD applied to the saturated dredger silt filled ground is researched.Finally,some useful conclusions are drawn,so as to provide for reference.
