| 摘 要： | 珠江三角洲河网纵横交错,网河河道的泥沙来源既有上游不同径流挟带的陆域来沙,也有潮流所挟带的海域泥沙,河道水动力和冲淤特性极为复杂。以广州出海水道上段(广州-黄埔段)为例,在分析河道不同径潮组合下河道水动力特点的基础上,采用二维潮流泥沙数学模型对工程所在河道的极限冲刷进行了模拟计算。研究表明,对于三角洲复杂网河河道,认识不同的径流条件下河道的水动力特点是研究河道冲淤特性的前提。

| Abstract: | The river network in the Pearl River Delta area is rather complicated.The sand from two directions,both the inland sand by the upstream runoff and the sand by the tide from the sea,has complicated the hydrodynamic and sand deposit situation.Based on the study of the hydrodynamic changes under the different runoff situation,the 2-D tide current and sediment mathematical model has been set up to calculate the limit scour situation,taking the waterway section from downtown Guangzhou to Huangpu as an example.It has been proved that the analysis of the hydrodynamic features under different runoff influence is the prerequisite for the study of the sand deposition in the river. |
