摘要
感潮河段因受上游径流和下游潮汐的双重影响,航道设计通航水位确定方法和标准需考虑两方面的因素,目前尚无定论。通过分析内河和海港设计通航水位确定方法的特点及异同,以长江、珠江等感潮河段水文站的实测资料为依据,分别按两种方法进行实例计算,探讨其适用性,并针对区段划分、标准确定及其衔接、样本资料取用年限等问题进行了分析。
Because of complex influence of runoff and tide in tidal reaches, how to make decision method and standard of designed navigable stage have not been known up to now. Features, similarities and difierences in the inland channel and seaport were analyzed. On the basis of measured data at reaches of the Yangtze River, Zhujiang River, etc., statisical calculation according to two ways was performed, and applicability of them was discussed. Then, some issues, such as section compartmentation, stage standard and its join, fixed number of year of the data, were studied respectively.
