摘      要：This paper investigates the interface mechanical behavior of flexible piles with L_p/D10 under lateral load and an overturning moment in monotonic loading *** modify the beam-on-Winkler-foundation model of piles in offshore wind farms,the energy-based variational method is *** soil is treated as a multi-layered elastic continuum with the assumption of three-dimensional displacements,the pile modeled as an Euler-Bernoulli beam.A series of cases using MATLAB programming was conducted to investigate the simplified equations of initial *** results indicated that the interaction between soil layers and the applied force position should be taken into account in calculating the horizontal soil ***,the distributed moment had a limiting effect on the lateral capacity of a flexible ***,to account for the more realistic conditions of OWT systems,field data from the Donghai Bridge offshore wind farm were used.
