软土地基中静压桩沉桩的力学特性研究

Study on the Mechanical Characteristics of Static Pile Sinking in Soft Ground Foundation

为研究软土地基中静压桩沉桩位移和应力应变的变化特性,以镇江地区软土地基为参考,结合Plaxis3D有限元数值模拟软件,建立软土地基静压桩沉桩的有限元模型,分析了在静压桩沉桩过程土体的变化规律,并探讨了不同荷载及不同贯入深度下桩周土体的应力应变变化情况,为实际静压桩沉桩过程提供理论基础和有效参考。

In order to study the variation characteristics of static pile driving displacement and stress and strain in soft soil foundation,the finite element model of static pile driving in soft soil foundation was established with Plaxis3D finite element numerical simulation software,and the variation law of soil in the process of static pile driving was analyzed.The stress and strain changes of soil around piles under different loads and different penetration depths are discussed,which provides theoretical basis and effective reference for the actual process of static pile driving.
