摘　　要：水下地形图是轨道交通工程规划、设计、施工的重要基础资料,本文以广州轨道交通三号线流溪河水下地形测量为例,阐述了广州市连续运行参考站城市3维定位系统(GZCORS)在水下地形测量中的作业模式、方法及精度。该种作业模式在河道、沿海港口等水下地形测量中有着广阔的应用前景。Underwater topographic map is an important material for the planning,design,and construction of rail transit project.Taking the underwater surveying of Liuxi River of line 3 of Guangzhou rail transit system as a case study,this paper elaborates on the operation mode,method and accuracy of 3D positioning system of Guangzhou CORS in under water surveying,which has a bright application prospect in the underwater surveying in rivers and coastal harbor.
