| 摘 要： | 介绍了基于潮汐模型与余水位监控的水位改正法在成山角东侧近海区域定线制多波束测量中的应用情况。结合本实例应用,总结了依适用性检测、验潮站布设方案设计、水位改正值计算等的实施步骤及技术细节。在本次测量中,由沿岸成山角站实现了邻近无潮点附近整个测区的水位控制,水位改正中误差约为0.064m。这证明潮汐模型在近海区域已能满足水深测量工程应用需求,且在严密论证的前提下可在工程实践中完全代替传统水位改正方法。

| Abstract: | A water level correction method based on the tide model and residual water level monitoring isemployed in the multibeam survey in the east of Chengshanjiao.The application steps and technical details aresummarized.The teps includes the applicability test,the distribution design of tidal stations and calculation of thewater level correction.The water level control of the total survey area near the amphidromic point is realized bythe coastal Chengshanjiao station,and the error in the water level correction is about 0.06 4.m.It proves that thetide model can meet the need of the offshore bathymetric survey,and the method can replace the traditionalmethods on the premise of rigorous evaluation. |
