This article aims to study the positioning technology of cable ducts for large-span cable-stayed bridges.By constructing a three-dimensional coordinate system based on bridge design parameters and construction requirements,and using Excel software programming and CAD modeling queries,the precise and rapid positioning of key points of cable ducts is achieved.At the same time,a positioning plate mold was designed based on the positioning characteristics of the cable duct,and auxiliary steel plate positioning technology was proposed to cope with complex conditions.Practical applications have shown that these technological achievements have effectively improved the accuracy and efficiency of cable duct positioning,providing reliable technical support for the construction of large-span cable-stayed bridges.
