摘　　要：沿海航路离岸远、跨度大,测量精度要求高,水位控制是影响沿海航路测量成果精度的关键因素。分析了中国沿海航路测量水位控制的特点和难点,结合辽东湾满载VLCC推荐航路扫测工程案列,探讨了验潮站布设、海上定点验潮站数据获取、深度基准面确定、水位改正等关键技术问题,并提出了适用的解决方案,提高了水位控制作业效率和成果精度,以期为中国沿海航路测量水位控制提供有益的借鉴。Coastal route is far from the shore with large span, which results in the demand of high precision survey.Water level control is the key factor of affecting accuracy of coastal route survey. This paper analyzes characteristics and difficulties of water level control in China＇s coastal route, discusses data acquisition, depth datum plane, water level correction and some other key technical issues by studying the data of the Recommended Rroute of VLCC in Liaodong Bay, and puts forward applicable solutions to improve the efficiency of water level control and the accuracy of the result. The conclusion provides a useful reference for further research on the water level control of China＇s coastal route survey.
