Abstract: This paper uses the measured load test data of the pipe pile of Huaneng Guanyun Offshore Wind Farm to verify the applicability of the four proposed p-y curve methods for clay. The parameters of p-y curves are obtained using cone penetration tests（CPT）. The comparison results show that the traditional p-y curve will significantly underestimate the ultimate resistance of the surrounding soil due to the limitations of the original test,leading to a conservative pile design,while the hyperbolic p-y curve may overestimate the soil resistance,therefore the initial stiffness can be accurately predicted. On this basis,model ensembling is used and a new p-y curve is established by combining the traditional p-y curve model with the hyperbolic p-y curve model. Finally,a case study is used to verify the reliability of the new p-y method. This method can provide a new way to analyze the lateral loaded pile in clay.
