Abstract

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.
