| 摘 要： | 利用无人测量船与网络RTK技术联合测量某一涵盖水陆区域的填挖土方量。其中，利用无人船系统测量水下地形，利用网络RTK测量陆地地形，并将水陆两部分的地形数据融合，利用基于不规则三角网的DTM法计算了该区域的填挖土方量，同时得到水域部分的水下地形图，为后续施工建设提供了基础资料。本文提出的结合无人船和网络RTK技术测量复杂水陆地形的方案可为相关工程的测量实践提供参考依据。

| Abstract: | The method of combining unmanned boat with network GNSS RTK technology is used to measure the topography and calculate the earthwork of an area, which coveres both land and water. The unmanned boat is used to survey the underwater topography, while the network GNSS RTK is used to measure the landform. Afterwards, the volume of earthwork is calculated through the method of DTM, which is based on irregular triangle network with the fusing data of landform and underwater topography, the underwater relief map is also obtained through the data of underwater topography, which is measured by unmanned boat. Both the volume of earthwork and underwater relief map can provide basis for project construction. The method of combining the unmanned boat and the network GNSS RTK technology proposed in this paper can provide an important reference for measurement practice of related engineering. |
