摘要

以2212号台风梅花为例,基于有限元数值模型,对位于江苏东台海域的海上风电场场址进行大小尺度模型嵌套的水动力-波浪-泥沙的耦合数值模拟,计算台风造成的风暴潮和风浪影响下的海床形貌演变趋势。结果表明：场区海床受台风影响下的冲刷和淤积程度比无台风情景下的结果更显著,在过境期间,台风能够增大海床的输沙率。采用数值模拟分析预测台风对海床造成的泥沙冲淤变化趋势,能对海上风电场海床泥沙冲刷风险评估以及海上风电场的安全保障和预测性运维提供科学的参考依据。

Abstract

In this paper, the typhoon Muifa （No. 2212） was selected as a case study. A three-way coupled hydrodynamic-wave-sediment numerical simulation was conducted using a finite element numerical model. This simulation involved the use of large-and-small-scale-nested models within an offshore wind farm site located in Jiangsu. The objective was to calculate the evolution trend of the seabed under the influence of storm surges and waves caused by the typhoon. The results demonstrate that the extent of scouring and siltation of the seabed in the site area under the influence of the typhoon is more pronounced than that under the no-typhoon scenario. During its passage, the typhoon enhances the transport of solid materials on the seabed. The use of numerical simulation allows for the analysis and prediction of the trend of sediment scouring and siltation caused by typhoons on the seabed. This provides a scientific basis for the monitoring and prediction of seabed scouring, as well as for the safety guarantee and predictive operation and maintenance of offshore wind farms.
