国内外港口工程深度基准面及码头面高程计算方法对比

Algorithm comparison about depth datum and jetty's elevation between domestic and overseas port project

全面总结了我国深度基准面的历史演变过程和基本算法,介绍世界各国深度基准面的分类和使用进展。同时,针对国内外港口工程码头面高程计算方法的差异,从计算原理、组合因素、资料分析等方面对比国内外计算标准的差异,对码头面高程计算中设计水位的定义和统计方法等进行细化分解,清晰了国内外标准使用中的异同,为准确运用国内外标准提供了有益的指导。

Making an overview survey about the historical evolution process and the primary algorithm of depth datum in our country, the paper introduces the classification and development of the depth datum worldwide. Meanwhile, the paper gives a comparison about the calculate algorithm of jetty＇s elevation between domestic and overseas code. It focuses on the calculation principle, combination factors and data analysis, and analyzes the definition and statistical approach of the design water level. This comparison research may be helpful to the application of domestic and overseas code in port projects.
