宁波沿海设计高潮位分析及查算图绘制

Analysis of Design High Tide Levels in Ningbo Coastal Area

选取宁波沿海16个潮位站作为代表站,采用年最高潮位极值Ⅰ型分布法、年最高潮位P-Ⅲ型分布法、极值同步差比法、高潮同步相关法四种方法进行频率计算,根据计算结果绘制不同海域设计高潮位查算图,为宁波市沿海地区工程建设提供参考和依据,也便于查求无资料地区的设计高潮位。

Selecting 16 representative tidal stations in the Ningbo coastal area, annual maximum extreme value distribution method, annual high- est tide level Pearson- Ⅲ distribution method, extreme difference ratio method, and high tide level synchronous correlation method were used to make frequency analysis. Then a chart of high tidal level in different coastal area according to the calculation results was developed, which can provide a construction reference for coastal engineering and design high tidal level of the area without observation data.
