高平潮水位传递在远岸水深测量中的探讨及精度分析

Discussion and accuracy analysis on water level transfer using high slack tide in far off-bank bathymetric survey

阐述了在远岸水深测量中采用高平潮法传递水位的原理、提出了该法应用的假设前提、分析了误差源,通过工程实例验证其可靠性,并分析了图载水深的主要误差源,给出了精度估算。工程实践证实,该方法合理解决了在大面积(100km2以上)远岸港口工程水深测量中水位控制的难题。

This paper expatiates the principle of water level method using high slack tied in far off-bank bathymetric survey,presents the applied hypothesis premise of this method,discusses its error sources,verifies its reliability through engineering cases,analyses the major error resources of charted depth,and gives the precision estimation.It is proved through engineering practice that by this method,the difficulty in bathymetric survey of large-area（over 100 km2） far off-bank is solved properly.
