一、引言本文根据全国沿海二十几个主要港口和100多个主要测站的大量潮位资料进行了分析,对国内外几种设计水位的统计方法作了比较和评述,对缺乏潮位资料或观测时间短且残缺不全的地区,如何推求设计水位作了论证,并对无资料地区提出了相应的推求设计水位方法。本文将计算海图深度基准面的BPF面的方法实际运用于推求设计水位,並编制了沿海主 I. INTRODUCTION Based on a large amount of tide data from more than 20 major ports and more than 100 major stations along the coast of China, this paper compares and comments on several statistical methods for design water level at home and abroad. Short time and incomplete areas, how to infer the design of the water level was demonstrated, and the lack of information on the region proposed the design of the water level method. In this paper, the method of calculating the BPF surface of the depth datum of the chart is actually applied to the design of the water level and the coastal master
