Abstract

Silt foundation in Kaifeng area was select as the research object, to verification the combination of foundation treatment for CFG pile + vibro-replacement stone column pile methods. The results showed that: engineering properties of the foundation soil between piles are improved after the CFG pile or vibro-replacement stone column composite foundation. More important, the liquefaction of silt foundation can be eliminated by treatment with CFG pile + vibro-replacement stone column pile. The foundation bearing capacity values were improved from 75 kPa (soil between piles) to 300 kPa (composite foundation), which meet the load requirements.
