摘　　要：结合传统的软土地基处理方法,提出利用高真空排水和击密施工交替进行的高真空击密法加速夯后超静孔压消散和软土固结,并结合黄河三角洲地区某吹填土地基进行了现场试验研究,对高真空击密法的工艺流程、试验参数、加固后的土体变形、超静孔压变化以及加固效果进行了分析。研究表明高真空击密法是一种工期短、效果佳、成本低的软土加固工艺,适合于黄河三角洲地区新近沉积的吹填土。Combining with traditional soft ground reinforcement methods,high vacuum compaction method of using high vacuum drainage and dynamic consolidation alternately to accelerate the dissipation of excess pore water pressure and the consolidation of soft soil was proposed.The in-situ test was studied for hydraulic filled ground reinforcement in Yellow River Delta region,and construction process,test parameters,soil deformation,excess pore water pressure and reinforcement effect were also analyzed.It is proved that high vacuum compact method is a time-saving,effective and low-cost soft soil reinforcement method,which can be suitable for hydraulic fills ground reinforcement in Yellow River Delta region.
