摘　　要：目前在实际工程中适用于计算管桩在水平荷载作用下的方法较少,且常用的m法和p-y曲线法也存在问题,对此提出一种PHC管桩单桩水平承载力的p-y曲线与有限层耦合计算方法。通过理论分析,阐明PHC管桩单桩在水平荷载作用下承载力的合理性;基于试验提出PHC管桩水平极限承载力的预测方法;通过比较不同计算方法得出的极限荷载值,证实p-y曲线与有限层法相耦合的计算方法能较准确地模拟水平荷载作用下PHC桩的工作特性。In practical engineering, the methods applying to calculate the pile under the horizontal loads are less, and the common method m and the p-y curve method exist many problems. Therefore, this paper proposes a p-y curve and finite interlayer coupling horizontal bearing capacity calculation method of PHC pipe pile. There is a certain value that it illustrates the rationality of the PHC Piles carrying capacity under horizontal load through theoretical analysis, the method basing on experiment is proposed to predict the level of ultimate bearing capacity of PHC pipe piles and the ultimate load value derived by comparing the different calculation methods confirms that the calculation methods of the p-y wears coupling finite layer can more accurately simulate the characteristics of the PHC pile under horizontal loads.
