摘　　要：为了预报和防御胶州湾受台风影响而造成的风暴潮灾害,本文基于Delft3D数值模拟软件和混合风场模型,以9711号台风为例,建立了青岛胶州湾及其附近海域在台风影响下的二维波流耦合数值模型,利用耦合模型模拟分析9711号台风对胶州湾影响过程中波流耦合增水极值对风暴潮以及胶州湾的影响,探究纯风生流表层流场的时空变化特征和波浪增水对风暴潮增水的贡献。结果表明:9711号台风对胶州湾引起的风暴潮水位中天文潮位占主导地位,波流耦合增水极值随着叠加天文潮位的降低而增大,综合水位随着天文潮的降低而下降;当波流耦合最大增水叠加天文潮高潮位时,胶州湾西北部海域形成漫滩的风险加剧;此外,胶州湾内浅水区域的波浪增水较深水区域更为显著。In order to forecast and prevent storm surge disasters caused by typhoon in Jiaozhou Bay,a two-dimensional nested wave-current coupling numerical model is established in Jiaozhou Bay and its adjacent sea area based on Delft3D numerical simulation software and mixed wind field model.Based on the coupling model,the influence of the extreme value of wave-current coupling surge on the storm surge and Jiaozhou Bay during the influence of Typhoon Winnie on Jiaozhou Bay was simulated and analyzed.The temporal and spatial variation characteristics of the surface flow field of pure wind-driven current and the contribution of wave surge to storm surge surge surge are explored.The results indicate that the astronomical tide level is dominant in the storm surge water level caused by typhoon 9711 in Jiaozhou Bay.The extreme value of wave-current coupling increases with the decrease of superimposed astronomical tide level,and the comprehensive water level decreases with the decrease of astronomical tide level.The maximum increase of wave-current coupling and the high tide level of astronomical tide aggravate the risk of forming an inundation at the northwest of Jiaozhou Bay.In addition,the wave surge in the shallow water area of Jiaozhou Bay is more significant than that in the deep water area.
