摘　　要：沉桩挤土效应是岩土工程领域研究的经典和难点问题,如何有效预测和控制沉桩挤土效应,是学者不断探索的课题。以某桩基工程为研究对象,基于Plaxis有限元软件,采用位移贯入法,分析了沉桩挤土过程中土体的水平位移和竖向位移的变化规律,特别分析了淤泥质土的影响,为软土地区桩基工程设计与施工提供了参考。Abstract：Pile squeezing effect is one of the classic and difficult problems in the field of geotechnical engineering, how to predict and control pile squeezing effect effectively is a topic which scholars continue to explore. Taking a pile foundation engineering for the study, based on Plaxis finite element software, using displacement penetration method, analyzing the variation law of horizontal and vertical displacement on the process of pile driving, especially analyzing the influence of muddy soil, which could provide some references for the design and construction of nile foundation in soft soil area.
