桩土相互作用时桩参数对大直径空心桩承载影响的有限元研究

FEM Research on Affection of Pile Parameters to the Bearing Capacity of Large Diameter Hollow Pile in the Case of Pile-soil Interaction

运用Ansys有限元技术,分析了在竖向荷载作用下大直径空心桩桩顶沉降、桩端沉降与桩身压缩三者的关系,桩长L对桩身轴力的影响,桩长L、桩径D、桩体弹性模量E对桩P-s曲线的影响,桩长L、桩径D对桩P-Se(桩端沉降与桩顶沉降的比值)曲线的影响,具有工程上的实际意义。

The paper analyzed the large diameter hollow pile under vertical loading on the relation among settlement of pile top, settlement of pile end and pile shaft compression with Ansys finite element technique.
