【摘要】：在进行水位改正前,需要确定各潮位站的基面,制作海图中常使用理论最低潮面作为基准面,但由于临时潮位站无法与地面控制点联测,确定临时潮位站的理论最低潮面需要通过传递计算。介绍的传递计算方法主要包括:内插法、潮差比法和综合传递法。采用在长期站旁设置临时站的实验,比较了3种方法的计算结果,最后确定了适合长江口滩涂地区临时验潮站理论最低潮面传递的计算方法。
[Abstract]:Before the water level correction , it is necessary to determine the base surface of each tide station , make the lowest tide surface of the theory in the chart as the reference surface , but because the temporary tide station cannot jointly measure with the ground control point , it is determined that the lowest tide plane of the theory of the temporary tide station needs to pass the transmission calculation . The transfer calculation method introduced in this paper mainly includes : interpolation method , tidal difference ratio method and comprehensive transmission method . The calculation result of 3 methods is compared with the experiment of setting temporary station beside the long - term station . Finally , the calculation method suitable for the lowest tide surface transmission of the temporary tide tide station theory in the tidal flat area of the Yangtze River Estuary is determined .

【正文快照】： 0引言水位改正是海道测量的基本技术之一,其本质是将瞬时实测水深值扣除海面变化的影响,从而得到不受时间变化影响的从某个固定基准起算的水深值[1]。海图中水深的起算面称为海图深度基准面,它也是水深测量水位改正的起算面,我国一般使用理论最低潮面作为该基准面[2],同时海图
