运用ABAQUS有限元软件详细模拟了预应力管桩沉桩过程引起的超孔隙水压力分布及消散规律，讨论了其随时间变化过程、有效应力增加随超孔压消散变化规律，并与Vesic理论解进行了对比分析，研究了预应力管桩沉桩过程中桩周土体超静孔压的变化规律。可为同类工程的设计和施工提供参考。

The principal view of this article is to discuss the excess pore water pressure distribution over tine, the effective stress increases with the dissipation of excess pore pressure variation. This paper demonstrates the comparison between the pore pressure variation and Vesic cylindrical expansion theory by using ABAQUS finite element software to simulate the discipline of excess pore water pressure distribution and dissipation of the pile driving process. The changing rules of excess pore water pressure were studied, which would provide an important basis for the design and construction of the similar projects.
