论感潮河段航运工程水文标准分界与衔接

Studying on dividing and connecting of the hydrology standard between river and sea navigation engineering

  • 摘要: 针对中国河流与海岸交界处感潮河段航运工程水文标准存在的问题,特别是设计水位的确定及其衔接和水流、泥沙分析方法的差异,进行区段划分和标准衔接关系的研究.通过阐述感潮河段区段及基本特征,分析了各类航运工程的水文指标,提出以"月平均潮位年变幅多年平均值" 和"多年平均潮差"两特征值的比值作为感潮河段不同区段划分的依据指标,并通过实例计算,论证了航运工程水文标准分界及其衔接关系.结果表明,该指标反映了感潮河段不同区段水文条件受径流和潮汐的影响程度,依据其不同取值,可对航运工程水文标准予以分界,形成较好的衔接.

     

    Abstract: Aiming at problems existing in hydrology standard for navigation engineering of tidal reach, especially difference and junction of confirmation of the design water level and research of flow and sediment for seaport and inland navigation engineering, studying on demarcation and connection of hydrology standard of tidal reach was performed. Through expounding the basic features of the tidal reach, hydrology factors of all kinds of navigation engineering were analyzed. Then, the ratio of two characteristic values that are annual average of in-year variation amplitude of monthly average water level and annual average of tidal range, was presented as a dividing index of different sections in the tidal reach. By means of case study and calculation, demarcation and connection of the hydrology standard of two kinds of engineering was demonstrated. The result shows that the ratio reflects the influence of runoff and tide to hydrology condition in different sections. The hydrology standard of two kinds of engineering in tidal reach can be divided and connected preferably according to its different value.
