［摘要］卡塔爾盧賽爾體育場主體結構為鋼結構受壓環連接魚腹式環向張力索桁架的空間大跨結構，為控制施工精度，合理安排施工工序，采用Midas Gen和ANSYS有限元分析軟件相結合，對施工過程進行模擬分析。分析結果表明，主體結構在施工過程中會產生較明顯的偏移。以分析結果為依據，采用“分階段精度控制，誤差分段化處理”的策略，配合可調節點的設計，可消化前道工序的誤差，避免誤差累積，最終確保膜結構和幕墻結構的順利安裝，實現設計目標。

Abstract: The main structure of Qatar Lusail Stadium is a large span truss structure. It is formed by compression ring connecting with fish tail radial cable truss and ring cable system. In order to control the construction accuracy and arrange the construction sequence, Midas Gen and ANSYS are used to conduct construction finite element simulation. The analysis result shows that the steel structure nonnegligible movement during the construction. On the basis of the analysis result, a strategy of control the accuracy and consume the deviations by stages is used to guarantee the construction accuracy and avoid the deviation accumulation. A set of adjustable connection design is also introduced to achieve the successful installation of membrane and fa-ade structure.
