The special feature including the mechanism of combined vacuum and surcharge preloading method for soft ground improvement is described. The soft ground improvement work in Huaihe River Zhangma Watergate project is investigated. Based on the field monitoring data (including surface settlement
settlement at different strata
horizontal displacement
pore-water pressure and degree of vacuum)
in-situ tests(including CPT
STP
vane shear tests and static load tests) and laboratory tests
the effect of ground improvement is analyzed and assessed. The results satisfy the design requirements. The study provides a reference for similar ground improvement projects using the proposed method.
