【摘要】：珠江口伶仃洋是地貌条件独特、水沙条件复杂的敏感海区,也是我国乃至世界沿海航线最密集、船舶密度最大的水域之一;港珠澳大桥是横跨伶仃洋的由"桥-岛-隧"构成的超级大型复杂工程。针对港珠澳大桥工程对珠江口伶仃洋复杂的水沙动力环境的影响,采用多种研究手段对大桥工程对伶仃洋水域水沙环境、港口航道、滩槽稳定性影响等关键问题进行全面深入系统的研究论证。主要研究成果表明:1)珠江口伶仃洋具有"微变性、趋稳性、可塑性"的重要特征,其"三滩两槽"基本格局可以长期保持稳定;2)港珠澳大桥(推荐方案)对珠江口伶仃洋水沙环境不利影响相对较小,对港口航道基本无不利影响;3)从水沙条件角度来看,港珠澳大桥(推荐方案)工程的建设是可行的。
[Abstract]:Lingdingyang in the Pearl River Estuary is a sensitive sea area with unique physiognomy and complicated water and sediment conditions. It is also one of the most dense coastal routes and the largest density of ships in China and the world. The HongKong-Zhuhai-Macao Bridge is a super large complex project composed of "Bridge, Island and Tunnel" across the Lingdingyang. In view of the impact of the bridge project on the complex hydro-sediment dynamic environment in the Lingdingyang River Estuary of the Pearl River Estuary, The effects of the bridge project on the water and sediment environment in the Lingdingyang waters, the port channel and the stability of the channel are studied systematically and comprehensively. The main research results show that the Lingdingyang in the Pearl River Estuary has "microvariability". The important feature of stability and plasticity is that the basic pattern of "three beaches and two troughs" can be kept stable for a long time) the Hong Kong-Zhuhai-Macao Bridge (recommended scheme) has relatively little adverse impact on the environment of the Lingdingyang water and sediment in the Pearl River Estuary. From the point of view of water and sediment conditions, the construction of Hong Kong-Zhuhai-Macao Bridge (recommended scheme) is feasible.
