针对湛江某海上风电场风电机基础冲刷防护问题,选取目标风电桩基,对其周边进行多波束扫测,结合实际海床情况设计了抛石、废旧轮胎和仿生草3层复合装置,对装置进行陆地实验和实海测试,实验结果表明该装置完全符合冲刷防护装置安装要求,可进行实际现场应用。该复合型冲刷装置整合了单一形式防冲刷装置的优势,可根据风电机基础海床情况调整,可有效防止二次冲刷,防护效果更优。
Abstract
Regarding the issue of scour protection for the foundations of a certain offshore wind farm in Zhanjiang, a target wind turbine foundation was selected, and multibeam sweeping was carried out on its periphery.A three-layer composite device consisting of riprap, waste tires and bionic grass was designed in combination with the actual seabed conditions. Onshore experiments and offshore measurements were carried out for the device. The results of the experiments show that the device fully meets the requirements for the installation of scour proteltion derices. It can be used in actual field applications. The composite scour device combines the advantages of a single form of anti-scour device. It can be adjusted according to the seabed condition of the turbine foundation, which can effectively prevent secondary scour and provide better protection.
