摘要：
The supercharged vacuum pre-pressure method is to increase the supercharge system on the basis of the direct vacuum pre-pressure, and to increase the pressure in the middle of the vacuum process, thus achieving the goal of saving efficiency and increasing construction costs. Based on the reinforcement project of a blowout foundation in Lianyungang, this paper analyses the process of soil surface subsidence, pour water pressure, stratified subsidence and groundwater level when the soft foundation is reinforced by supercharged vacuum prepressing method by field test method. The paper will provide data support for future actual projects.
