砂土中水平桩不同 p-y 曲线尺寸效应研究

摘要

Through field test,assessing the accuracy of deformation of three popular p—y models by the pile-head’s load-deformation curve. And another experiment data are used for the analysis of the bending moment. This paper will draw conclusions that help to study the lateral loaded piles of different diameter,and provide advices for design of large-diameter piles.%通过现场水平受荷桩试验，评测现有砂土中 p—y 曲线模型准确性随着桩径增加或变形增加的精度，并选用现场实验数据，评测三种 p—y 曲线模型预测桩身弯矩的精度，该结果可广泛应用于工程中砂土不同直径水平受荷桩的非线性分析，为大直径的水平桩受荷分析提供建议。
