摘　　要：p-y曲线法常用于水平受荷桩研究,但因其参数获取不易而制约了发展。而静力触探经研究证明可用于水平承载性状分析。因此本文通过建立p-y曲线法中的敏感参数与静探数据之间的综合对应关系,提出基于静探的p-y曲线法,并对照某近海地区软土地层的水平试桩资料及利用Abaqus进行桩土作用仿真计算,验证了基于静探的p-y曲线法的适用性。本文提供了基于静探的单桩水平受荷桩研究的简便方法,为相关工程提供了参考依据。p-y curve method commonly used for the study on laterally loaded piles,while it is restricted the development for the difficult to obtain its parameters.CPT has been proved that it can be used for horizontal baring analysis.This paper proposes a new method based on the CPT and establish the correspondence between the CPT and p-y.By comparing the horizontal pile test data of soft soil and the pile-stimulation based on Abaqus in a offshore area,the applicability of p-y curve model based on CPT is verified.This paper provides a simple and convenient method for studying piles based on CPT,and provides a reference for related projects.
