Studies of the Numerical Simulation of Sediment Scour for Wind Power Station in Intertidal Zone

摘要

Dafeng wind power station was chosen as the study area. 2D mathematical model of total sediment transport and erosion-deposition model were established by considering the joint action of wave and current. The models were verified by the measured data of the project. The verified model was applied to simulate the engineering problem. The transformation of flow field was calculated firstly, and then the erosion-deposition of engineering zone and the thickness of scour near foundation piles were simulated respectively in terms of the following three different conditions: normal condition, under the action of strong southeast wind and the action of uttermost east wave. The results of simulation can provide strong basis for the project.
