[摘要]卢赛尔体育场是2022年世界杯主场馆。屋面主索网为双层轮辐式全张力结构,该张力结构通过双层拉环和双层压环与48榀鱼腹式径向索桁架连接而成。选用上环索提升加两阶段径向索提升的方案。通过全景模拟仿真计算,分别确定环索提升和径向索提升最不利工况组合并据此选定提升工装。施工期间,严格按照全景模拟仿真计算结果从提升开始直至安装就位全过程进行索力和位形监测。

Abstract: The Lusail Stadium is the main stadium for 2022 World Cup. And the roof main cable net is whole tension structure of double layer spoke type, which is composed of double layer tension rings and double layer compression rings to connect with 48 pieces fish tail radial cable truss. The author selected the method of lifting upper tension ring plus two phases of lifting radial cable. By calculation of whole process simulation, the worst critical cases of both lifting tension ring and lifting radial cables and selected the lifting tools accordingly is confirmed. During the construction, the calculation results of whole process simulation is strictly considered from commencing of lifting to the end of pin installation to monitoring the tension forces and displacements.  

Keywords: stadiums;steel structures;main cable net;tensioning tools;simulation;monitoring
