摘　　要：分析了江苏如东海域烂沙洋南水道的稳定性,建立了基于不规则三角形网格有限差分法的江苏如东海域大范围和小范围嵌套二维潮流数学模型,在对模型验证的基础上,对西太阳沙人工岛工程的陆岛通道实体堤合理长度进行了潮流场数值模拟研究。研究结果表明,烂沙洋南水道主槽基本上是稳定的,从潮流场和烂沙洋南水道的稳定性角度考虑,陆岛通道实体堤合理长度应不超过6 km.2-D tidal flow nested mathematical models of coastal waters at Rongdong, Jiangsu Province, are set up, which include a larger domain model and a smaller domain model inside the larger domain. The models are generally based on irregular triangular grid and the finite difference scheme. On the basis of model verification against field measured data, studies are carried out on the rational length of dam from shore to artificial island at Xitaiyangsha shoal by tidal flow numerical modeling. The study results show that the rational length of dam from shore to artificial island at Xitaiyangsha shoal is not more than 6 km.
