| 摘 要： | 对钱塘江强潮河段江道缩窄治理进行研究。首先,回顾治理方案的比选,江道全线缩窄时河轴线线路和河道宽度的确定原则,以及不同河段的指数放宽率。然后,介绍了在涌潮汹涌、滩涂淤坍变化剧烈的强潮河段,实施筑堤所采取的工程措施的步序与要点。最后,分析论证了大规模江道缩窄治理后河床、潮汐、洪水位及涌潮高度等特征值的变化。可供进一步深入理论研究和工程施工参考运用。

| Abstract: | River bed regulation in strong tidal reaches of the Qiantang river is studied.Firstly,comparison and selection are made for regulation schemes,and confirming principles on river axes line and width during river bed narrowing,and broadening ratios on exponent for different reaches,etc.Secondly,introductions are given on the sequence and essentials of engineering measurements of the embankment for strong tidal reaches with tidal bore surges and strong beach silting and collapsing.Lastly,characteristic variations are analyzed of tide and flood water table and height of tide bore after large-scale river bed narrowing.The research affords a base for further theoretical research and engineering construction reference. |
