摘要
通过系统整理长江口滞流点研究的相关文献,分别从实测资料、数学模型及物理模型等角度总结滞流点研究主要进展。并以时间顺序分析滞流点位置在各时间段的变化趋势,分析表明:多年来滞流点位置活动范围基本不变,但不同流量级下存在一定的上溯或下移。该项研究对认识工程影响下长江口河段水动力变化有重要意义。
Through systematically organizing the related literatures of the study about the stagnation point,this paper summarizes the main progress of the study about the stagnation point through different approaches which are the measured data,mathematical models and physical models,Then,in chronological order,it analyses the trends of the location of the stagnation point in each time.The analysis suggests that the location of the stagnation point did not change its range over years,but sailed upstream and downstream under different flow conditions.This paper has great significance in understanding the hydrodynamic changes in the Yangtze Estuary under the influence of the engineering works.
