岛群海域渔港建设原则数学模型

Numerical modeling on the construction principle of fishery port at the multiple islands sea area

通过分析自然条件,结合波浪、潮流泥沙数学模型试验手段,以宁波石浦港区为例,探讨了在岛群海域中建设渔港的水动力、泥沙问题及对应的方案布置原则。研究成果表明,在多岛屿、强流速海域建设工程时,应尽可能利用天然水深,避免浅滩开挖导致的回淤,并充分利用岛屿掩护,减少波浪对工程区域的作用。航道及码头前沿线的选取宜与潮流主轴平行,以规避较强的航道横流及泊位处开、拢流的影响。

Based on the analysis on natural condition and the numerical model test of wave, tidal current and sediment, taking the Shipu Port of Ningbo as an example, we discussed the hydrodynamic force and sediment problems in the construction of fishery port at multiple islands sea area, and studied the principle of the project layout. The results show that when constructing fishery ports at the sea area with multiple islands and strong flow velocity, we should use natural water depth to avoid the dredging as far as possible in order to reduce the siltation, and make full use of the island shield to reduce the waves in engineering area. The axis of the port and channel should be parallel to the major direction of the natural tidal currents in order to reduce a strong cross flow in channel and the open and close flow in berth.
