水平荷载下桥梁基桩设计计算及工程应用

摘要

从水平荷载作用下桥梁基桩的破坏模式入手,着重分析不同类型桩在水平荷载作用下的承载特性及变形破坏机理.根据水平荷载作用下桥梁基桩的受力特性,建立了双层地基中基桩内力与位移分析的计算模型,并通过幂级数法对其进行求解.通过某工程实例对其中的桥梁基桩进行计算分析.以期为类似工程的设计与施工提供参考.%Bearing characteristics and deformation mechanism of bridge piles under horizontal loads were analyzed using the failure mode. The calculation model of internal forces and displacement analysis in the layer foundation was established, and its solutions were obtained by power series method. The correctness of the calculation method was verified in a practical project. This work can provide a reference for the design and construction of similar projects.
