摘要
架空输电线路三维模型设计是开展输电线路施工、运行仿真模拟的基础,文中介绍了输电线路模型组成,包括导地线、绝缘块、杆塔等多种子模型,并针对工程实际案例进行设计研究,利用智能航测系统进行航空采集,建立输电线路走廊DOM及DEM数据,同时采用BIM技术对输电线路建模,形成完整三维模型。最后将研究成果与实测结果对比,研究表明该输电线路三维设计有利于开展路径优化工作,使工程测量更加快捷准确,具有一定应用价值。
The 3D model design of overhead transmission lines is the basis for the simulation and construction of transmission lines.This paper firstly introduces the model composition of transmission lines,including various sub-models such as grounding lines,insulating blocks and poles,and then,designs for actual engineering cases.The intelligent aerial survey system is used for aviation acquisition,establishing the DOM and DEM data of the transmission line corridor,and the BIM technology is adopted to model the transmission line to form a complete three-dimensional model.Finally,the research results are compared with the measured results.The research result shows that the three-dimensional design of the transmission line is conducive to the path optimization and engineering measurement is faster and more accurate,and has certain application value.
