摘要
简述了无验潮测深技术的原理和方法,对该技术在河湖水下地形测量中影响成果质量的主要问题进行了分析和探讨,同时提出了实用可行的质量控制方法。
The principle and method of sounding technology without tide gauge are briefly described;the main influence factors for the quality of underwater topographic survey during using this technology in river and lake are analyzed and discussed.Meanwhile,a practical and feasible method of quality control is proposed.
