通过对长江芜湖站水位资料的整理,用JTJ213-98《海港水文规范》和GB50139-2004《内河通航标准》这两类规范的不同方法分别计算芜湖段设计最高和最低通航水位,结果表明,同一站点的感潮河段,按照不同方法计算得到的设计通航水位差异很大。对结果分析,比较后,提出用内河规范的频率法确定芜湖段设计最高通航水位,用内河规范中的综合历时曲线法确定设计最低通航水位。
According to the data of Wuhu station on the Yangtze River, the highest and lowest navigable water levels of Wuhu section were calculated by different methods of JTJ213-98 “Harbor Hydrological Regulation” and GB50139-2004 “Inland Navigation Standard”. The results show that the same The tidal reaches of the site, according to different methods of calculation of the design of navigable water vary widely. After analyzing and comparing the results, it is proposed that the maximum navigable water level for design of Wuhu section should be determined by the frequency method of river regulation, and the minimum navigable water level should be determined by the integrated diachronic curve method in river regulation.
