珠江口伶仃洋深水航道开发方案的回淤研究

摘要:
根据伶仃洋的潮流、含沙量及水下地形的变化特点,对黄埔出海航道在伶仃洋的选线方案作了分析计算。选用泥沙回淤计算公式预报了各航道开挖后的回淤量。用伶仃西航道和蛇口五湾航道开挖后的实测结果进行淤积验证,计算值与实测值符合较好。伶仃东航道泥沙的回淤量少于伶仃西航道;铜鼓东航道也少于铜鼓西航道。无论开发伶仃东航道或是在伶仃西航道原来的基础上加深,均为可行。

Abstract:
Based on the characteristics of tidal flow, suspended sediment concentration and the topographic change under datum of the Lingdingyang, the analytical calculation for the scheme selection of the Huangpu-seaward navigation channel in the Lingdingyang sea is carried out. Predication of siltation of every study navigation channel is performed.Calibration is made before using the formula developed by author for the calculation of the channel sedimentation, it is shown that the calculation values are closely agree with those measured in the prototype. From the amount of siltation, which in the east channel of Lingdingyang is less than that in the west channel, also siltation in the east channel of Tonggu is less than that in the west channel. But from the point of development and requirement, it is the same fessibility either developing the east navigation channel or deepening the west channel on the basis of its original depths.
Key words:  navigation channel,siltation, siltation calculation
