竖桩和斜桩在拱式桥梁工程中的应用比较

本文对斜桩受力及承载力计算进行了探讨 ,并通过对竖桩和斜桩的受力比较 ,认为在拱式桥梁工程中斜桩受力比竖桩受力有利 ,因此 ,拱式桥梁桩基可采用带有一定倾斜角度的斜桩来承受拱座垂直反力与水平推力 ,可不再设台后阻滑板 ,减少工程开挖量 ,节省工程投资。

Conparison of Application of Plumb Pile and Battered Pile in Arch-Type Bridge Project

The paper approaches to the calculation of the forced and bearing capacity of battered pile.And through the forced comparison between plumb pile and battered pile it thinks that the battered pile is favorable more than plumb pile in forced aspect in arch type bridge project.Therefore,battered pile with a certain oblique angle can be used for arch type bridge pile foundation to bear the vertical reversed force and the horizontal pushing force of the arch skewback.It can without anti sliding plate at the rear of abutment,reduce the excavation quantities of the project and save the investment of the project.
