摘要

用解析方法研究了管桩在轴向力和水平向力（倾斜力）联合作用下的受力及变形性状。在高层建筑、桥梁工程、海洋工程、新型海堤护岸等工程中桩基自由长度上作用土压力、风荷载、波浪荷载等荷载型式，基桩经常在竖向、水平向荷载同时作用下工作。国内外学者通过大量试验和理论研究得出了计算竖向、水平向荷载下基桩内力和挠度的半经验公式以及张氏法公式。为了分析竖向、水平向荷载同时作用下自由荷载的作用，在现行m法假设的基础上，从弹性桩的挠曲微分方程出发，导出了任意自由荷载作用下桩任意截面的水平变位、倾角、弯矩、剪力和地基反力计算表达式。桩的挠曲微分方程是分段函数，包括地上部分和地下部分桩，相应的内力和变位求解也分为两段。最后通过一个算例分析了桩顶竖向荷载、桩顶水平力和自由荷载对桩身的受力性状各参数的影响。计算结果表明

桩顶水平力对桩身最大弯矩和桩顶水平变位的影响最大，而桩周内外摩阻力及桩身自重对桩身受力性状影响较小。

Abstract

The analytical solution of a single pipe pile under axial and lateral loads is presented

when the lateral load is optional free load. As pile foundation is becoming a preferred foundation type in high buildings and wide-span bridges

piles usually work under simultaneous axial and lateral loads(inclined loads) in engineering

then increasing efforts is being focused on the behavior of piles under inclined loads. Semi-empirical formula and Zhang’s formula have been used to calculate pile’s behavior under inclined loads by scholars at home and abroad through practical and theoretical studies. To analyze the function of free loads to pipe piles under inclined load conditions

on the basis of m method

deformation differential equation of elastic piles under inclined loads is established first with analytical method. Differential equation has two parts according to the piles in the earth or in the air

and lateral deformation

obliquity

moment

shearing force of the piles can be gotten respectively by solving the equations. Finally

influences of the top axial loads

the top lateral loads and the free loads

on several parameters are analyzed; and their influence curves are given.
