| 摘 要： | 用JTJ214-2000《内河航道与港口水文规范》和JTJ213-98《海港水文规范》这两种不同规范的方法分别计算长江下游感潮河段设计最高和最低通航水位,并对计算结果进行了对比分析,发现南京和江阴是设计通航水位选择规范方法时两个重要的分界点.同时还对感潮河段在计算设计通航水位时所需样本年限问题进行了探讨.研究结果表明,感潮河段设计通航水位方法的选取以及所需样本年限的长短与其距河口的距离有密切关系.

| Abstract: | The highest design navigable stage and lowest design navigable stage of the tidal reach of the lower Yangtze River were calculated by use of the two methods according to Code of Hydrology for Inland Waterway and Harbor (JTJ214-2000) and Code of Hydrology for Sea Harbor(JTJ213-98). The comparison of the calculated results shows that Nanjing and Jiangyin are two important separation points in selection of reasonable design codes for navigable stage design. Meanwhile, the age of data for calculation of design navigable stage was discussed.It is indicated that the distance from the tidal reach to the estuary should be highly concerned in determination of data age and selection of methods for navigable stage design. |
