摘要

摘要: 以国网江苏省电力有限公司500 kV凤城—梅里长江大跨越工程输电高塔施工为背景,研究提出了一套基于有限元模拟与计算机视觉的输电高塔组立施工新技术。首先根据吊装构件特点、安装位置等制定合理的吊装与安装工艺流程,再建立关键施工阶段铁塔与抱杆的耦合有限元模型,在铁塔与抱杆结构上布置实测监测系统采集风环境和结构状态的多元信息,保障施工安全开展。为解决抱杆高空作业位移测量难度大的问题,研发了一种高空结构物相对位移的计算机视觉位移测量方法。采用有限元模拟结构整体受力变形状态,结合计算机视觉技术对施工动态过程开展结构变形和位移测量,提出了输电高塔组立安全高效施工新技术。

Abstract: With the background of the construction of the transmission tower crossing the Yangtze River of Jiangsu Fengcheng-Meili 500 kV line, a set of construction and erection techniques for transmission towers based on finite element simulation and field measurement was proposed. First of all, according to the characteristics of lifting components, installation location, etc., a reasonable lifting and installation process was developed, and then a coupled finite element model of the tower and the crane in the key construction stages was established, the real measurement system was installed on the tower and crane structure to collect the dynamic information of the wind environment and the structure state, so as to ensure that the construction could be carried out safely. A computer vision displacement measurement method of relative displacement of overhead structures was developed to solve the problem of difficult displacement measurement of crane at high altitude. The finite element model was used to simulate the overall state of the structure, the computer vision method was used to measure the deformation and dynamic displacement of the structure, a new safe and high-efficienly technique for construction and erection of transmission towers was proposed.
