| 摘 要： | 以珠江口南沙港区挖入式港池为例,通过数学模型模拟了港池的水体交换状况,模拟结果表明港池尾部水体交换率最低。利用港池内外存在潮位差的关系,通过人工水渠的方式有效提高了港池尾部水体的交换速率,有效解决了挖入式港池水体交换缓慢的问题。

| Abstract: | The excavated-in harbor basin of Nansha Harbor area in Pearl River estuary was taken as an example.A mathematical model was employed to simulate the water exchange in the harbor basin.The simulated results indicate that the rate of water exchange is very low at the tail part of the harbor basin.Based on the differences of tidal ranges inside and outside the harbor basin,and artificial canal is adopted to significantly improve the rate of water exchange at the tail part of the harbor basin and to effectively... |
