Saturated silt soil foundation treatment with dynamic consolidation is used in Baogang Steel Co.,Ltd.in Nantong city of Jiangsu province. This paper mainly studies the dynamic consolidation parameters and foundation treatment effect in the design and construction process with a series of tests.Different dynamic consolidation parameters are adopted in different project areas,including monitored tamping pit settlement,ground uplift amount,as well as the pore water pressure in the consolidation process.Based on the static cone penetration test and static load test after consolidation process,this paper compares the reinforcement effects under different dynamic consolidation parameters,and at last gets the silt soil foundation dynamic consolidation parameters adapting to this project.
