摘　　要：杭州奥体中心体育游泳馆长约609m,宽约200m,由下部主体混凝土结构和屋盖钢网壳结构组成。介绍了工程的结构体系、设计难点和主要分析结果。着重阐述了设计中的一些关键问题及相应的处理措施,包括结构的超限情况及抗震性能化设计、屋盖自由曲面钢网壳设计、有粘结预应力梁设计、温度应力计算和弹塑性分析等。The sports and swimming stadium of Hangzhou Olympic Center is about 609m in length and 200m in width. It consists of the main concrete structure at the bottom and the steel reticulated shell roof. The structure system, difficuhies in the designing process, and the main analysis results of this project are introduced. Some key points are focused on during the designing process, including the situation of this beyond-code-limits structure, the seismic design, the design of free- form surface steel reticulated shell roof, the design of bonded prestressed beams, the calculation of thermal stress, and the elastic-plastic analysis, etc.
