| 摘 要： | 短期同步验潮具有操作简单、容易实施的优点,可以达到厘米级高程传递精度,是一种非常有效的高程传递技术。利用国家海岛(礁)测绘工程临时验潮站水深测量数据,对相距较远的验潮站之间海水面变化的相关性进行了分析研究,给出了部分海岛同步验潮水深、水深差以及水深差与均值之差的变化规律和波动幅度,通过与三角高程的高差结果比较,外符合核精可达到5cm,对于利用短期同步验潮实现高程传递的工程实践具有重要的参考作用。

| Abstract: | Short-term tidal synobservation is an available method when doing the elevation transmission over the sea with obvious excellences of easy operating and actualizing, and could realize centimeter-grade elevation transmission.This paper uses the temporary tidal observation depth data of the island-mainland connection surveying project,analyzes and researches the fluctuating law of the instantaneous sea level and their correlation character.Compared with the trigonometric leveling,this paper gives the discrepancy of two methods when doing the elevation transmission over the sea,also gives the precision of the actual measurement,which provides the important reference for the project using short-term tidal synobservation to realize the elevation transmission. |
