基于无人机摄影测量技术的四维施工管理研究

Research on Four Dimension Construction Management Based on Unmanned Aerial Vehicle Photogrammetric Technique

不断提高工程建设管理水平是国家电网公司对输变电工程的一贯要求。青藏交直流联网工程建设面临高寒缺氧、地质复杂、冻土广布三大难题,如何在复杂的建设环境下确保工程质量,建设世界高原输电精品工程,对施工过程的管理提出了更高要求。为提高管理效率、提升管理水平、强化工程质量、保障工程安全、保护生态环境,保证工程顺利实施,在青藏交直流联网工程建设中,探索利用无人机摄影测量技术辅助施工管理,即在传统的三维信息系统的基础上,采用无人机航摄技术,获取施工建设期间的地表特征变化,以及环评水保等多种专题信息,增加时间维度,实现施工建设的四维管控,辅助施工过程管理,为决策指挥提供支撑,提升工程建设全过程精益化管理的程度,促进工程建设施工管理水平和效率的提升,实现了工程建设管理手段的创新。

Continuous improvement of power transmission project construction management level is a consistent demand of the State Grid Corporation of China.The construction of Qinghai-Tibet AC/DC interconnection project meet with the problems of alpine hypoxia,widespread permafrost complicated geological conditions and other many difficulties as well as poor traffic.In order to ensure the construction quality of the project,it is necessary to strengthen the construction process management.Therefore,we present a solution for construction management of power grid engineering based on UAV photogrammetric technique in the project.It can improve the level and efficiency in management,and preserve the ecological environment.It helps push forward the innovation of construction management.
