Embodiment 1
[0046] Located in a dredger reclamation area in Ezhou, Hubei, the average depth of dredger reclamation is about 3~6m. The newly dredged silt has the characteristics of high water content, high compressibility, poor water permeability and extremely low initial bearing capacity. Before treatment, the moisture content of the soil in the test area was greater than 150%, and the wet density was 1.43g / cm 3 , liquid limit 92.6%, plastic limit 39.1%; particles larger than 0.075mm accounted for 2.7%, 0.075mm~0.005mm accounted for 52.1%, and less than 0.005mm accounted for 45.2%; The force is close to 0, and it needs to be used as a foundation after treatment. The bearing capacity of the treated foundation is required to be greater than 55kPa. In addition to forming a shallow hard crust of about 1m, the reinforcement depth is also required to be at least 2m.
