摘　　要：本文介绍了澳门综合体育馆钢结构屋盖主桁架的整体提升方案,并对提升方案中提升架设计、提升过程及支座就位等相关技术问题进行了探讨和分析。介绍了提升架的结构形式及稳定承载力验算,据此提出了格构柱整体稳定性的通用计算方法;应用ANSYS软件对钢结构屋盖主桁架的整体提升过程进行了模拟动态跟踪分析,确定提升过程中应力和变形的变化范围,以此判断提升方案的可行性;对提升过程部分构件的应力和变形进行了实时监测,其测试结果与理论计算结果吻合较好,积累的经验和数据可为类似结构的整体提升提供借鉴。The integral lift design of the main trusses of steel roof in Macao Gymnasium and the analysis of their latticed hoist tower are presented in this paper. Some key technical problems are outlined and analyzed. The corresponding measures taken to solve these problems are proposed. First, the structural form and analysis method of overall stability load-carrying capacity of the latticed hoist tower are decided. Then a unified design approach is proposed for checking the overall stability of all possible latticed hoist tower schemes. Based on the ANSYS finite element program, the continuous check of the modulation of deformation and stress distribution in the main truss during the lifting process is monitored and traced, thus to ascertain which lift method is feasible to apply to construction. The stresses and deformation obtained from the FE model are compared with the measured results, and a good agreement is obtained. Through this engineering project, some experiences and data in lift technology are accumulated and they may be employed in the construction of similar steel structures.
