摘　　要：本文采用ADCIRC和SWAN模式建立了基于非结构网格的深圳海域高分辨率天文潮-风暴潮-海浪耦合数值模型。基于历史统计资料,以1604号台风“妮妲”作为基础路径、以1319号超强台风“天兔”作为设计强度设计了超强台风,计算了超强台风影响下深圳西部海域的最高潮位,结果显示宝安机场、赤湾和深圳湾顶的最高潮位为5.71 m、4.67 m和5.06 m,分别超过当地红色警戒潮位2.69 m、1.65 m和2.98 m。为验证波浪增水作用设计了敏感性实验,结果显示波浪对风暴潮增水的贡献量值约0.1 m。A high-resolution tide-storm surge-wave coupling numerical model for Shenzhen is established with ADCIRC and SWAN.The design super typhoon is chosen considering the worst track"Nida"and the most intensity"Usagi"based on historical data.The highest water level caused by the design super typhoon in the western waters of Shenzhen is calculated.The computational results show that the highest tide level of the Baoan Airport,Chiwan and the top of Shenzhen Bay is 5.71 m,4.67 m and 5.06 m,respectively,which are 2.69 m,1.65 m and 2.98 m beyond the local warning tide level.An sensitivity experiment is designed to study the effect of the wave on the surge,the result of which indicates that the surge caused by wave is merely 0.1 m.
