摘要 对现有的p-y曲线简化计算方法进行了归纳与总结.通过在水平静力荷载作用下淤泥质黏土中钢管桩的模型试验研究,并结合实际工程案例分析,比较采用各类计算方法对实验数据处理后的土抗力分布,以及拟合p-y曲线.结果表明,采用分段3次拟合法得到的土抗力分布曲线更为合理.各类计算方法拟合的p-y曲线均低于API建议曲线.随着土层深度的增加,采用分段3次拟合法得到的p-y曲线更加贴近于实际理论曲线分布. This paper summarizes the existing p-y curve simplification calculation methods of single pile.Through the model test study of steel pipe pile in muddy clay under horizontal static load and the analysis of practical engineering cases,the distribution of soil resistance and fitting p-y curve after processing the experimental data by each kind of calculation method are compared.The results show that the soil resistance distribution curve obtained by piecewise cubic fitting method is more reasonable.The p-y curve fitted by each calculation method is lower than the curve recommended by API.With the increase in soil depth,the p-y curve obtained by piecewise cubic fitting method is closer to the actual theoretical curve distribution.
