摘要:横向荷载桩可以用傅里叶有限元来分析。这个方法适用于嵌入在具有恒定或者线性变化模量的单层弹性土和具有恒定模量的双层弹性土的桩。桩的反应是桩、土相对刚度和桩长细比的函数。基于分析提出了描述弹性长桩与短而粗的刚性桩的挠度、转角和最大弯曲力矩的设计方程。通过桩-土刚度比和长细比的函数绘制了桩的反应图后，这些设计方程被进步一开发。反应图也可以用来设计表格。最后通过设计的案例说明了此分析方法是正确的。

Abstract: Laterally loaded piles are analyzed using the Fourier FEM. The analysis is performed for piles embedded in single-layer elastic soil with constant and linearly varying modulus and in two-layer elastic soil with constant modulus within each layer. The pile responses were ob-served to be functions of the relative stiffness of pile and soil, and of the pile slenderness ratio. Based on the analysis, equations describing pile head deflection, rotation, and maximum bending moment are proposed for flexible long piles and stubby rigid piles. These design equations are developed after plotting the pile responses as functions of pile-soil stiffness ratio and pile slenderness ratio. These plots can also be used as design charts. Design examples illustrating the use of the analysis are provided.
