摘要
探讨高桩码头桩基的稳定与确定桩计算长度、附加弯矩的问题,提出排架各桩顶水平弹性系数的分配方法,使高桩码头桩基可分解为桩顶带水平弹簧、转角为固定或自由的单桩计算,探讨了确定桩计算长度需要考虑的一些因素,提出设计建议取值并与建筑规范进行了比较,分析了建筑规范存在的问题,提出如何考虑桩的水平力或水平位移计算桩的附加弯矩等问题。
The article discusses the pile length and additional bending moment of piles. foundation stability of piled wharf and determination of calculated It also puts forward the allocation methods for horizontal elasticity coefficient of each pile top of bent so as to convert pile foundation calculation of piled wharf to single-pile calculation which is classified into three types： pile top with horizontal spring, fixed comer or free comer ones. Moreover, factors needing consideration in determining pile＇s calculated length and method for calculating additional bending moment are studied.
