| 摘 要： | 莱州湾具有典型的大陆架结构，潮汐性质复杂。本研究根据莱州湾沿岸4处典型验潮站的多年数据计算了各站深度基准面值及保证率，并与相关涉海部门现采用值进行了比对分析。结果表明：个别验潮站计算值与相关涉海单位采用的深度基准面值有明显差异。本文就此进行了分析并提出了合理性建议。4处验潮站周边均埋设了高等级水准点，通过历年实施的高等级水准联测来监测各站高程基准点变化量，计算结果可用以维持区域垂直基准，为今后莱州湾港口建设、航道施工、水深测量、船舶通航及信息发布等提供更加准确的基础资料。

| Abstract: | Laizhou bay is a typical continental shelf structure with complex tidal properties. Based on the data of four typical tide gauge stations along the coast of Laizhou Bay, this study calculate the datum value and guarantee rate of each station, and compared them with the current values adopted by relevant marine departments. The results show that there are obvious differences between the calculated values of individual tide stations and the depth datum denomination adopted by relevant sea-related marine units. To resolve the problem, some reasonable suggestions are proposed. High-level benchmarks are buried around the four tide stations. The change of elevation benchmark of each station is monitored through the high-level leveling continuous survey over the years. The calculation results can be used to maintain the regional vertical benchmark and provide more accurate basic data for Laizhou Bay port construction, channel construction, bathymetric survey, ship navigation and infor mation dilivery in the future. |
