摘　　要：简述了现代海洋水深测量的基本特点;定性和定量地分析了由船速效应、波浪效应、定位中心偏心效应,以及测深仪发射声波延迟效应等测量环境效应引起的测量误差;推导了测量环境效应误差改正公式。计算机数值模拟结果表明,波浪效应是引起水深测量误差的主要因子。针对海洋水深测量环境效应的特点,提出了一些提高测量精度的方案和建议。Depicting the basic characteristics on modern bathymetric surveying,qualitatively and quantificationally analyzing the errors caused by the bathymetric surveying environment effect,which includes vessel speed,wave,eccentricity of positional antenna center and sounding delay,this paper establishes the mathematic model of error correction for bathymetric surveying.The results of computer simulation indicate that the wave is the main factor causing the errors in bathymetric surveying.Aiming at characteristics of effects with bathymetric surveying environments,some schemes and advices are recommended for increasing accuracy of soundings in a bathymetric survey.
