摘　　要：重庆市游泳、跳水馆屋盖设计采用四角锥焊接空心球节点钢管网壳。平面形状为梭形 ,长轴 2 0 8m ,短轴 82m ,屋盖为平面两条圆弧线 ,脊为一条圆弧线 ,沿脊的方向形成无数个圆组成的空间曲面 ,两端悬臂段的悬挑长度分别为 3 2 75 ,2 8 80m。主要介绍了该工程屋盖的结构选型、支座弹性刚度的确定 。The roof of the natatorium of Chongqing adopts quadrangular pyramid with welding hollow sphere joints. It's shuttle shape with 208 m long major axis and 82 m long minor axis. The roof is formed with two arcs. An arc moves along the ridge and forms the curve face. The two cantilever are 32 75m and 28 80m long. This paper mainly introduces the choice of the structural system, the confirmation of base elastic stiffness,the affection of various base elastic stiffness on the inner force of the latticed shell and some important problems.
