【摘要】 岱山岛位于舟山群岛中部,地理位置优越,具有通江达海的区位优势。为满足舟山北向的水路客运需求,拟在岱山岛北侧建设燕窝山码头工程,包括码头和防波堤。文章根据现场实测资料分析,建立了舟山岱山岛燕窝山码头工程及其附近海域潮流泥沙数学模型。在模型验证的基础上,计算了不同防波堤布置方案下码头工程及其附近的流场和泥沙淤积情况,对现有防波堤平面布置方案对水流和泥沙输运的影响进行分析,并选出合理解决方案。从水流、泥沙计算结果看,燕窝山和东垦山的北海域流速较大,超过2.0 m/s,5 m等深线以内水流流速较小,在0.6 m/s以内,故码头工程对岱山海域整体流态影响不大,其是可行的。但根据航道横流流速变化特征,应增大航道设计宽度,保证船舶航行安全。更多还原

【Abstract】 Located in the middle of the Zhoushan Archipelago, Daishan enjoys a superior geographical position. Breakwaters and docks will be built on the northern side of Daishan in order to meet the water transport needs. Based on field measurement data, the dock project and its mathematical model of Yanwoshan, Daishan were established with hydrodynamic equation. The model can calculate the flow field and siltation situation under different breakwater settings. According to the analysis of the impact of existing breakwater layout schemes and sediment transport, a reasonable solution will be selected. The results shows that the north sea of Yanwoshan and Dongkenshan has a large flow velocity exceeding 2.0 m/s, and the flow velocity within the isobath of 5 m is small, within 0.6 m/s and sediment calculation, the dock project is feasible. However, the designed width of the fairway should be increased to ensure the navigation safety of the ship according to variation characteristics of cross flow velocity in channel.更多还原
