摘　　要：中国海洋大学综合体育馆屋面结构为双曲抛物面结构,该体育馆为承办第十一届全运会篮球的比赛场馆,是青岛市的重点建设项目之一。结合该工程结构特点和现场施工条件提出了一种新的网架施工方法——运用条形支撑悬臂扩展拼装技术,避免了布置满堂脚手架而影响下部施工,利用ANSYS软件对起步单元稳定性条件、扩展拼装顺序、悬臂拼装网格的大小进行了系统的分析,针对该网架提出了采用该施工方法起步单元的稳定性条件、拼装顺序以及拼装网格的个数。The comprehensive gymnasium of the Ocean University of China is a hyperbolic paraboloid steel grid structure constructed for the 1 lth National Basketball Games. It is one of the key construction projects in Qingdao. To develop the installation scheme, the characteristics of the structure and construction site were considered, and a new construction method which is cantilever extended assembly technology with a strip-type support frame was used for the grid structure to avoid the erection of full hall scaffold effects on lower construction. The stability factor of starting elements, cantilever expansion sequence and the size of the element were analyzed by using ANSYS softwares. The stability requirement of the starting unit, sequence of expansion and the number of the expanding units were put forward for the structure in this construction method.
