Abstract

Based on the bounding surface cyclic p-y model, the cyclic p-y spring element for soft clay is developed by using the user-defined element （UEL） interface of Abaqus software. The developed spring element is used to establish a finite element model of the interaction between large-diameter monopile and soft clay ground. Then, dynamic responses of monopile foundation under asymmetric horizontal cyclic loading are systematically investigated. The developed p-y spring element can effectively simulate the nonlinear hysteresis, plastic displacement accumulation and stiffness degradation characteristics of soft clay. The numerical simulation results show the evolution of pile head displacement, mud surface rotation angle, pile deflection and bending moment with the number of cycles under asymmetric cyclic loading, and reveal the influence of cyclic loading mode and loading level on the pile response. The research results deepen the understanding of the interaction mechanism between horizontally loaded pile and soil, which can provide a certain reference for the design of large-diameter monopile foundation for offshore wind turbines.
