| 摘 要： | 随着航道建设规模和航道里程增加,长航道乘潮水位的计算成为航道设计遇到的新技术难题之一。针对多潮位站控制长航道乘潮水位计算问题,提出了乘潮水位计算的多站联合典型潮曲线法。通过构建典型潮曲线,使乘潮累积频率、乘潮历时、潮波传播延时和潮波变形等关键要素同时呈现。基于构建的典型潮曲线,进一步探讨了长航道全程同一乘潮水位、分段变乘潮水位,以及进港、出港等不同情况下乘潮水位的设计取值方法,并以珠江崖门航道为例进行了实例分析,进一步说明了本方法的实用可行。

| Abstract: | As the scale of navigation channel becomes larger, the calculation of ridable high tide level for long navigational channel is a new problem encountered. According to the calculation of ridable high tide level for the long navigational channel, the united multi stations typical tidal curves based on the statistical analysis are presented. Many key elements such as cumulative frequency, tide rising duration, tidal propagation delay and deformation are showed in the working drawing. By the method, the same or variable ridable high tide levels for the long navigational channel are presented. The example of Yanmen Approach Channel shows the calculation method is practical and feasible. |
