摘要
该文在分析风浪与河口滩槽泥沙运动、河口滩槽演变和航道骤淤等研究现状的基础上,通过建立波流共同作用下的三维悬沙数学模型,以珠江口高栏港区深水航道为例,探讨大风天泥沙运动和航道骤淤规律。研究结果表明:计算值与实测值基本吻合,并预报了50年一遇情况下航道的骤淤情况。从大风浪影响滩槽变化的角度,提出了一种预报海岸河口淤积以及骤淤的一种有效途径。
On the basis of analyzing the river estuary shoal sediment movement, trough evolution, sudden siltation, the sediment movement and channel sudden siltation rules are studied under big waves through establishing the three-dimensional suspended sediment mathematical model under wave current interaction, with the deep-water channel of Gaolan Port area of the Pearl River as an example. The research results show that the calculated values agree well with the measured values, and the 50-year-return-period channel sudden siltation is predicted. Considering the influence of big waves on trough change, effective method of predicting coastal and estuarine siltation and sudden siltation is put forward.
