摘要
通过夯扩挤密桩对新近回填的杂填土和素填土进行加固处理,消除了地层的湿陷性和其下的液化层;并利用夯扩桩与CFG桩共同作用形成复合地基提高了地基承载力,达到了设计目的。
The collapsibility is controlled when the new refilled .soil is reforced by tamped and enlarged pile. At the same time, the upper .sand liquefaction is controlled too. The foundation bearing capacity is improved by the interaction of CFG pile and tamped and enlarged pile.
