摘　　要：无人船测深系统的发展和使用已有一定的基础,但在城市地区的线性工程水下测量部分一般是采用人工或单波束方式采集水下地形数据,传统的技术手段虽然可以保证数据的正确性,但是也存在诸多不足。本文在上海轨道交通二十号线项目中,通过华微6号无人船测量系统采用多种方式获取了隧道越江处的水深数据,通过对误差数据的多种分析,证明多波束测深精度得到有效控制,能够完全满足在工程测量中的应用,同时形成多种数据成果填补了智能化全息测绘水下测量的空白和为实景中国建设提供了基础。The development and use of unmanned vessel sounding systems have a certain foundation,but in urban areas,the underwater survey part of linear engineering generally uses manual or single beam methods to collect underwater terrain data.Although traditional technical means can ensure the accuracy of the data,there are still many shortcomings.In this paper,in the Shanghai Rail Transit Line 20 project,the water depth data at the crossing of the river in the tunnel was obtained through various methods using the Huawei 6 unmanned vessel survey system.Through various analysis of the error data,it has been proved that the accuracy of multi-beam bathymetry has been effectively controlled and can fully meet the application in engineering surveying,At the same time,various data achievements have filled the gap in intelligent holographic surveying and underwater measurement,and provided a foundation for the construction of Real China.
