摘　　要：有验潮模式的水深测量可以获取高精度的水位数据,但验潮仪易丢失、破坏,会导致验潮数据丢失或不可用,造成极大的经济损失和时间成本。GPS-RTK无验潮模式水深测量可实时获取水面高程值,可避免因无水位数据导致的测量工作失效和经济损失。在GPS-RTK有效工作范围内的水深测量,可采用这两种测量模式同步进行,当验潮仪受到破坏时则采用无验潮的测量结果,既避免了经济损失又能按时提交测量数据。本文以国外某河道项目为依托,对其测量流程进行梳理和研究,以探明GPS-RTK无验潮水深测量结果的精度如何。Bathymetric survey in tide mode produces high-precision data on water level,but the loss and damage of tide gauge lead to lost or unavailable data,huge economic loss and time waste.Bathymetric survey by using GPS-RTK in non-tide mode may produce real-time water surface height,and avoid any failure or economic loss caused by unavailable data on water level.Within the effective range of GPS-RTK,bathymetric survey can be carried out simultaneously in the above two modes.Once tide gauge is damaged,the survey result in non-tide mode can be adopted,which not only avoids economic loss but also guarantees the submission of survey data on time.Based on an overseas waterway project,the survey process is sorted out and studied so as to find out the accuracy of GPS-RTK bathymetric survey in non-tide mode.
