摘要: <正>采用ANSYS有限元软件对抗拔桩施加预应力效果进行了定性分析,并通过现场测试结果验证,得出抗拔桩中施加预应力对桩身受力有明显效果,预应力使桩身产生压应力,其压应力自桩顶和桩底向桩身中部逐渐减小,为预应力抗拔桩的设计和应用提供有益的依据。

Abstract: A qualitative analysis for tension pile with prestress was taken by applying the AN- SYS software and by a field experiment. The result shown that the prestressed tension has obvious effect. The prestress resulted in a compressive stress in the pile body, which was de- creasing from the top and the bottom to the middle of the pile body. This would provide a foundation for the design and application of prestressed tension pile.
