| 摘 要： | 介绍了珠江河口整体潮流泥沙物理模型的主要特点.通过局部动床冲刷及悬沙淤积试验,研究了港珠澳大桥修建前后伶仃洋滩地的演变情况.研究结果表明:港珠澳大桥修建后主流区附近桥址断面局部河床将出现明显的冲刷调整.与无工程相比,工程后伶仃洋各主要浅滩10年累积淤积厚度有所增大,但量值较小；主要浅滩发展速度呈增大趋势,但变化幅度不大.工程实施后,伶仃洋三滩两槽的总体格局基本保持不变.

| Abstract: | This paper describes the main features of the physical model of the Pearl River Estuary tidal current and sediment.With the local moving bed erosion and suspended sediment deposition in the trial,the evolution of Lingdingyang Beach before and after the construction of Hong Kong-Zhuhai-Macao Bridge has been analyzed.The results show that: after the construction of Hong Kong-Zhuhai-Macao Bridge,the local riverbed scouring situation in the sections of the mainstream near the bridge site has adjusted.After the construction is completed,the decade-accumulated deposition thickness of Lingdingyang shallows increases,but the value is smaller;the shoal development speed tends to increase,but the change is slight.In summary after the implementation of the project,the overall patterns of three beach and two slots in Lingdingyang bay remain essentially unchanged. |
