摘要
为掌握杆塔的整体变形情况和变形规律,提出一种基于三维激光扫描技术的输电杆塔变形观测方法。结合工程实例,通过对杆塔点云数据和设计模型进行对比,获取塔基不均匀沉降、塔身整体倾斜和塔材挠度变形信息,并分析输电铁塔的形变情况。结果显示,三维激光扫描方法能较好地分析铁塔整体变形,得到铁塔变形的准确值,为输电线路铁塔的安全运行提供了一种高效、高精度的监测方法。
A method of deformation observation of transmission tower based on 3D laser scanning technology is presented in this paper.It introduces the method of analyzing the data of tower point cloud and the design model to obtain the information such as uneven settlement of tower foundation,tilting of tower body,deflection and deformation of tower,and combined with engineering examples to illustrate.The results show that the point cloud data acquired by 3D laser scanning can analyze the deformation of the tower as a whole and provide an efficient and high precision application method for the safe operation of the transmission tower.
