采用自编软件COASTTOOL计算了天津港内潮流运动,在此基础上采用粒子追踪法模拟了港内外水交换过程,分析了现有港口水交换存在的问题,并提出有效交换长度的概念,以表征水体平均交换距离。针对原港区水交换存在的问题,提出了将北端全部打开的设想,从粒子交换计算结果看,北港池北端打开后水交换能力将有效改善。

Tianjin Port tidal movement is calculated by using COASTTOOL software. On the basis of the computational results,the water exchange process inside and outside the port is simulated by using particle-tracking algorithm (PTA). The water exchange problem of the existing ports is analyzed,and the concept of effective exchange length(EEL)is proposed to quantify the average exchange distance of water. A proposal to open the north end of the basin is put forward against the above water exchange problem. According to the calculation results of particle exchange,to open north end of the north basin of Tianjin Port will improve the water exchange capacity greatly.
