本文介绍了单桩在水平单调桩头荷载作用下的一系列模型试验结果。采用水力坡度相似技术，在模拟地应力条件下进行了砂土模型试验。研究重点是根据P-y曲线考察影响桩-土相互作用的各种因素。结果表明，P-y曲线具有高度的非线性和应力水平依赖性，但对桩头荷载条件不敏感。在低于一个桩径的深度处，P-y曲线被归一化为最大土杨氏模量Emax和桩径。将实验P-y曲线与美国石油学会(API)推荐的P-y曲线进行了比较。结果表明，实验测得的P-y曲线与API的P-y曲线有显著差异。提出了建立P-y曲线的新方法，并通过对观测模型桩响应的数值分析进行了验证。结果表明……
This paper presents results from a series of model tests of single vertical piles subjected to lateral monotonic pile head loading. Model tests were carried out in sand under a simulated field stress condition using the hydraulic gradient similitude technique. Studies were focused on examining various factors that affect the soil-pile interaction in terms of P–y curves. It was found that the P–y curves are highly nonlinear and stress-level dependent but are insensitive to the pile head loading conditions. The P–y curves at depths below one pile diameter were found to be normalized by the maximum soil Young's modulus Emax and the pile diameter. Comparison was made between the experimental P–y curves and those recommended by the American Petroleum Institute (API). It was found that the experimental P–y curves were significantly different from the API P–y curves. New procedures for constructing P–y curves are proposed and verified by numerical analyses of the observed model pile response. The results indicat...
