Abstract: 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.
Keywords: high vacuum compact method; hydraulic fills; reinforcement; in-situ test
