海上风电单桩基础三维潮流数值模拟
Numerical Simulation of Three-Dimensional Tidal Current for Offshore Wind Power Single Pile Foundation
摘要
Abstract
In order to further study the local scour,provide important input parameters,and provide guidance for the structural design of offshore wind power single pile foundation and the design of local anti-scouring scheme,the MIKE 3 HD software is used to establish a three-dimensional hydrodynamic model in the eastern sea area of Zhanjiang.Through the verification of measured data,the plane and vertical tidal current fields near offshore wind farms and single pile foundations are simulated.The results show that during the flood and ebb tide of the wind farm,the influence range of the single pile foundation on the tidal current field in the engineering sea area is small,mainly concentrated within 50 m of the single pile foundation.The velocity of the upstream-downstream surface of the pile foundation is weakened,with a decrease of 0.1-0.5 m/s in the velocity of the uprush,and 0.1-0.7 m/s in the velocity of the downrush.The decrease of the velocity of the downstream surface is stronger than that of the upstream surface and the range is larger than that of the upstream surface.The flow velocity on both sides of the pile foundation increases by 0.1-0.2 m/s,and the increase is similar.In the vertical distribution,there is an obvious velocity weakening area on the upstream-downstream surface of the pile foundation.The vertical velocity in the weakening area is basically the same,and there is no obvious stratification.The influence range of the downstream surface is more than twice that of the upstream surface.There is an obvious velocity enhancement zone on the side of the pile foundation,and there is an obvious stratification phenomenon in the vertical velocity.关键词
