船舶吃水对水深测量的影响浅析

在水深地形测量工作中,有很多不稳定因素极易造成水深数据误差.其中测量船舶吃水不准确也是造成误差的原因之一,因此测深船的大小以及船型的选择很重要.根据实际工作经验,对各种测量船舶吃水变化引起的水深测量误差的原因进行分析,并提出各种情况下减少水深测量误差的方法,以提高水深测量精度.

Analysis on Influence of Ship Draught on Water Depth Measuring

There are many unstable factors which may cause errors of water depth data easily in the water depth terrain surveying work.Wrong draught of surveying ship is one of the erroneous reasons.Therefore the size and type of surveying ship are very important.According to the practical work experience,the reasons causing the depth data errors by draught changes of each kind of surveying ship are analyzed and the method which can reduce the error in various situations are also proposed in order to increases the wat...
