支盘桩抗压和抗拔特性的研究

A study of compression and extraction resistence behavior of squeezed supporting disk piles

在前期研究的基础上,分析了支盘桩高承载力和低沉降量的内涵。通过分析得出:在轴向压力作用下,支盘承受较大的荷载,支盘力占总荷载大约60 %以上,说明在承力上,支盘力控制着单桩承载力和沉降量的大小。在抗拔方面,由于支盘上方土阻力的作用,使支盘桩的抗拔力大幅度提升。

The significance of high bearing capacity and low subsidence of squeed supporting-disk piles are analyzed systematically in this present paper on the basis of previous studies, the results have shown that the supporting-disk bears a high load, making up over 60 % of the total one. It is explained there fore that the supporting-disk does dominate both bearing capacity and subsidence of a single pile. With respect to the supporting-disk pile is increased greatly owing to the action of soil resistence above the pile.
