Abstract

Research purposes: The purpose is to obtain characteristics of the action mechanism，the settlement and the load bearing of the pile － soil when reinforcing the deep buried soft soil by taking the comprehensive measures for providing the basis for determining the design calculation method．

Research conclusions: After inserting the plastic drainage board in the composite foundation of the cement deep mixing pile，the effects of the drainage and consolidation in the deep buried soft soil can be speeded up to speed up the completion of the foundation settlement to reduce the post － construction settlement，the displacement development in the side direction can be speeded up and it is closely related to the drainage condition，and the improvement of the strength of the foundation soil can be speeded up and the stress ratio of the pile － soil is obviously smaller than the composite foundation of cement deep mixing pile and it favors for giving the play the load bearing capacity of the foundation soil．
