珠江口伶仃洋航道的回淤分析

Analysis on the sedimentation of the Lingdingyang channel in the Zhujiang estuary

通过实测资料的统计分析 ,结合珠江口伶仃洋的动力地貌条件 ,对该航道的泥沙回淤特征进行了多方面的论证 ,得出回淤主要发生在航道开挖段北部、洪季淤积占全年 2 3以及航道增深后回淤并未成比例增加等研究结果 。

According to the statistical analysis on data from the field test, this paper presents the characteristic aspects of the channel sedimentation in the Zhujiang Estuary based on its dynamical physiognomy. The study results show that the sedimentation mainly occurs in the north of the dredged area, that the amount of sedimentation in the flood season accounts for nearly two third of the amount for the whole year, and that the amount of sedimentation does not increase proportionally after the channel deepening. This paper also gives the prospect for the further development of the channel.
