| 摘 要： | 通过模型试验,研究了从港池取水对港池水动力条件和港池冲淤变化的影响。港池工程的修建使附近海域的流场发生了变化,电厂取水使得港池附近外海海域及港池内部流速增加。潮汐条件下半封闭港池内泥沙回淤主要是涨潮及取水水流将泥沙带入港池内,引起港池淤积。在不取水时,港池内泥沙淤积较少,然后随着取水流量的增加,港池内淤积增多,在4台机取水时港池内淤积最大,而后随着取水流量的增大,港池内不淤或少淤范围增加,淤积量又随着取水流量的增加有所减小,并且在港池的主流区泥沙基本不发生淤积。

| Abstract: | Based on a physical model experiment,the effect of water intake from a port basin on the hydrodynamic characteristics and the sediment deposition in the port basin was studied.Experimental results show that the deposition of sediment in the semi-closed port basin under tides is contributed mainly by the tidal flood currents carrying sediment into the harbor region and the sediment settlling down along its way.The relationship between the amount of deposition and the intake has a turning point.First,the amount of deposition increases and then decreases with the increasing of intake. |
