LiDAR技术在电力线路勘测设计中的应用研究

Application of LiDAR Technology in Power Line Survey and Design

针对传统电力工程线路勘测外业测量工作量大、作业环境复杂、危险性高且周期较长的特性,提出在线路工程勘测设计过程中引入LiDAR技术的作业方法。以飞马D2000+D-LiDAR2000为研究对象,首次将LiDAR技术引入西南院在云南某500kV线路工程,探究其对测量外业的工作替代方法。研究发现:LiDAR可完全满足平断面图测量需求;对塔基地形、塔基断面测量可部分取代;对高等级交叉跨越方案制定具有极大优势,大大提高室内方案制定的准确性,降低外业难度水平。

Aiming at the characteristics of heavy workload,complex working environment,high risk and long period of field survey in traditional power engineering line survey,the operation method of introducing LiDAR technology into the process of line engineering survey and design is proposed.Taking the Pegasus D2000+LiDAR2000 as the research object,the LiDAR technology was introduced into a 500kV line project in Yunnan for the first time to explore its alternative method for field surveying.It is found that:LiDAR can fully meet the requirements of plane section survey;Topography and section survey of tower foundation can be partially replaced;It has great advantages in the formulation of high-level crossing and spanning plans,greatly improves the accuracy of indoor plan formulation,and reduces the difficulty level of field work.
