摘要:
在侧向受荷桩计算方法的基础上,提出了地面超载下邻桩侧向变形的共同作用分析方法,推导了关于侧向受荷桩内力和变形的微分方程,并编制了计算程序,对被动桩的内力和变形规律进行了研究。结果表明:(1)桩的变形随桩长增加而减小,但桩长超过合理桩长后,桩顶变形就趋于定值;(2)桩顶或桩端的约束条件仅对其附近小范围内的桩的变形和内力影响较大,对其他部位几乎没有影响;(3)桩的变形和内力受地面堆载的影响较大,与其大小呈线性比例关系,而与其距离呈非线性关系。因此在被动桩设计时,应选择合理的桩长并严格限制地面堆载的大小。
Abstract:
Based on the investigation of calculation for the pile under side load, the paper proposes the interaction analysis for the lateral displacement of the adjacent pile under ground overload, thus deriving the differential equation. The research also makes calculation program and studies internal force and deformation regulation of the passive pile. The result shows that with the increasing of the pile length, the lateral displacement of the pile top varies to smaller value; the constraint of the pile top and pile end on the lateral displacement and internal force of the pile body is shown only in a relatively small range which has no effect on other positions; lateral displacement and internal force of pile body are in linear proportion to the ground loading and in non-linear proportion to the distance between the ground loading and the pile. Therefore, it is necessary to choose a reasonable pile length and strictly limit the size of ground overload in passive pile design.
