基于短期验潮资料的新建港区设计潮位确定方法*

在沿海港口工程中,确定设计潮位是一项重要的基础工作。对于新建港区,往往只有短期验潮资料,需要借助附近主港的长期验潮资料,采用短期同步差比法和相关分析法计算设计高、低水位,采用相关分析法和K值法计算极端高、低水位。研究判断潮汐性质相似性的定量指标以及基于多个计算结果的设计潮位确定方法。该方法应用于皮口港区总体规划中,为新建港区设计潮位的确定提供了参考。

New method for determining the design tidal levels for a new port with short-term observed tide data

The confirmation of the design tidal level is an important and basic task in coastal port engineering.For a new port with short-term observed tide data only,the difference-ratio method and correlation analysis are used to calculate the design high/low water level,while the correlation analysis and K-value method to calculate the extreme high/low water level by long-term observed tide level data of the standard port nearby.This paper proposed quantitative indicators for judging the tidal similarity firstly a...
