摘要
潮位改正是多波束地形勘测中的重要环节。琼州海峡跨海工程中分别利用验潮潮位和RTK潮位进行潮位改正，对比结果发现初始RTK潮位改正后的数据存在较大偏差，最大可达1．5m。通过对RTK测量潮位进行姿态校正后，其结果与验潮潮住的偏差减小，可以控制在0．3m以内。5-6月的琼州海峡正是西南季风爆发时间，海峡海流的流向具有复杂性，涨落潮都伴随着较大的风浪，RTK潮位测量忽略风浪带来的影响是出现较大误差的重要原因。
Tidal correction is an important step in the topographic survey of muhi-beam. The sea-crossing projects of Qiongzhou Strait＇s tide level correction were made using tidal gauging and RTK tidal level correction individually. The data appeared bigger deviation using RTK tidal level correction which had reached 1.5 m. The deviation could be restricted within 0.3 m after the attitude correction of the RTK tidal level, which is close to the tidal gauging. Every year, the May to June is the season of the southwest monsoon outbreak. Thus the tide rising and ebbing are followed by large wind wave for the complexity of current, which is the important cause of deviation using RTK tidal level correction.
