                                  [摘要]盧賽爾體育場是2022年世界杯主場館。屋面主索網為雙層輪輻式全張力結構,該張力結構通過雙層拉環和雙層壓環與48榀魚腹式徑向索桁架連接而成。選用上環索提升加兩階段徑向索提升的方案。通過全景模擬仿真計算,分別確定環索提升和徑向索提升最不利工況組合并據此選定提升工裝。施工期間,嚴格按照全景模擬仿真計算結果從提升開始直至安裝就位全過程進行索力和位形監測。

                                  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.
