Abstract
Silt foundation of the power plant in Shangqiu area was select as the research object, to verification the effect of foundation treatment for CFG pile and CFG pile + vibro-replacement stone column pile methods. The results showed that: bearing capacity of the foundation was improved after the CFG pile or CFG + vibro-replacement stone column composite foundation, the characteristic value of subsoil bearing capacity increase from 111kPa to 256kPa or 332kPa, respectively. The value of bearing capacity increment after treatment by the two methods is in the same order of magnitude. However, the liquefaction of silt foundation can be eliminated by treatment with CFG pile + vibro-replacement stone column pile. It is concluded that the value of bearing capacity after treatment by the two methods is both meet the requirement of the auxiliary building in power plant, and which one is suitable is based on whether the building is sensitive to liquefaction.
