摘　　要：以无锡洛龙湾一号一期工程为背景,对静压桩施工引起的挤土效应进行有限元分析,得出了土体挤压的一般性规律,在此基础上改变静压桩参数,分析了桩截面、桩靴的变化对桩周土体不同位置、不同深度处位移、应力的影响,以期为静压桩设计与施工提供依据。Relying on Wuxi Luolongwan the first project as the background, the soil-compaction effect caused by statically-jacked pile construction is analyzed by the finite element method, and the general rules is concluded. Based on that change the parameters of statically-jacked pile, analyze the effects of different position, different depth place displacement and stress caused by changing pile section or the pile shoe, and pro- vide the basis for design and construction of statically-jacked pile.
