在半月潮周期内,同样的总泄量以不同的分配方式下泄,会产生不同的抑制咸潮上溯效果。利用磨刀门咸潮物理模型,进行多种不同流量配置方式对咸潮上溯的影响试验。试验结果表明:半月潮咸界上移的阶段增大流量能有效的抑制其上涨幅度,压咸流量配置以小潮后的中潮阶段为宜。 During the half moon tide period, the same total discharge volume will be released in different distribution modes, which will produce different effects of salt water upstream tracing. By using the physical model of Saber Gate salty tide, a series of experiments on the effect of different flow patterns on the salt water upstream are carried out. The experimental results show that increasing the flow rate during the upward shift of the salty boundary of the half-moon wave can effectively reduce the rate of increase, and the distribution of salty flow rate in the middle tide stage after the tidal wave is appropriate.
