| Abstract: | 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. |

| Keywords: | sand liquefaction critical N-value tamped and enlarged pile |
