Abstract
The wire system performance facility project for the opening and closing ceremonies of the 7th Military World Games spans the Wuhan Sports Center venue,which is mainly composed of three parts,steel tower,anchor ingot,main cable.A double-deck segmented main cable system is adopted,and the span arrangement is(40+380+40)m.Using finite element software,the whole construction process of wire system is calculated and analyzed,and the installation method of double-deck sectional main cable is determined,which provides a technical support for the adjustment of main cable force and line shape in each construction stage,and realizes the line shape of main cable installation.At the same time,through technical research,preassembly design,factory manufacturing and on-site preassembling are adopted to ensure the assembling accuracy of steel towers,the UAV traction pilot cable guarantees the safety of the cable membrane structure of the gymnasium,and the transverse circulation traction system improves the installation efficiency of the main cable.This study provides a guarantee for the safe and rapid implementation of the project,and provides valuable experience for the construction of similar structures.关键词
