| 摘 要： | 位于斜坡上的桥梁桩基,由于桩基斜坡下方的土体在桩基纵向水平的挤压作用下,土体会产生滑移,甚至破坏,土中最大弯矩和弯矩零点深度会增加,桩基边缘与坡面的距离,现行规范没有具体的规定和要求,有些文章提供了经验值,但经验值没有考虑荷载的影响,本文主要利用桩土相互作用机理,对桩土作用效用进行探讨,并提出与荷载相关的斜坡桩基边缘与坡面的距离计算式,供同行在设计中参考。

| Abstract: | Bridge pile foundation locates in the slope.The soil mass,which locates below the pile foundation slope,can create slippage,even be destroyed under the longitudinal and horizontal squeezing action of pile foundation,the maximum bending moment and bending moment zero depth will increase,the distance between the pile edge and slope has not specific regulations and requirements in current codes.Though some articles provide empirical value,influence of the load is not considered.In this paper,role in the effect... |
