摘　　要：兴凯湖是中俄界湖,湖区流场和波浪场的观测数据及相关研究工作十分匮乏。针对兴凯湖典型风况下波流耦合数值模拟问题,在兴凯湖风场及湖水位特征分析的基础上,首次采用Delft-3D模型对兴凯湖流场和波浪场进行耦合数值模拟,分析了流场和波浪场的结构,并与太湖实测流场进行了对比分析。另外,利用相关规范中的公式计算了流场和波浪场的相关水力要素,验证了数值计算结果。经分析认为,波流耦合作用是兴凯湖北岸泥沙淤积、湖岸冲蚀破坏的主要原因。研究成果对兴凯湖北岸的防护工程建设及水资源保护具有重要意义。Xingkai Lake is a boundary lake between China and Russia and the observations and research about flow field and wave field are very scarce. For studying the wave-current coupling in Xingkai Lake under typical wind condition, on the basis of analysis for wind field and characteristics of water level at Xingkai Lake, Delft-3D simulation model was first used to analyze the structure of flow field and wave field of the lake and the analysis results were compared and analyzed with the measured flow field of Taihu Lake. In addition, the formula in correlative codes was used to calculate the hydraulic characteristics of flow field and wave field and verify the numerical calculation. It is concluded that the main cause of lake sediment deposition in the north side and lakeshore erosion is the interaction of wave and current.
