APPLICATION AND DEVELOPMENGT IN ENGINEERING PRACTICE OF LIME-SOIL COMPACTION PILE AND DOWNHOLE DYNAMIC COMPACTION (DDC) PILE

DDC pile is a new type of compaction pile, this paper exhibits a living example of soil improvement using lime-soil pile and DDC pile in a power plant. After analyzed and compared in compaction mechanism,compaction effects,bearing capacity and anti-deformation character of composite foundation, stability under soaking of composite foundation etc. furthermore, explores application and development of oompaction pile composite foundation.
