摘要
长江口南港长期以来是一条上下贯通、水深条件良好的入海通道。长系列水沙、地形实测资料表明,近期南港河段发生了一系列的河势变化,突出表现在瑞丰沙下沙体的冲刷和中部串沟的发展。在近期河床演变特征、演变趋势分析,以及南港12.5 m深水航道回淤特性分析的基础上,研究南港航道的整治策略,并提出初步治理方案。
The south channel in the Yangtze River estuary has always been a good access to the sea with favorable water depth condition. Long series of field data on water, sediment and topography show that a series of regime variations has happened in the south channel, such as scouring in the lower Ruifeng bar and development of central string ditch. Based on the analysis of the recent riverbed evolution characteristics, evolution trend, and siltation characteristics of the 12.5 meters deep water channel of the south channel, we research the regulation strategy of the south channel and put forward the preliminary regulation scheme.
