摘　　要：贯穿深圳宝安体育场整个结构设计流程,对各阶段遇到的主要问题进行研究。初步设计阶段,从建筑外观、体育场功能、结构特性和施工难易程度等角度比选3种方案。方案验证阶段,结合理论分析与宝安体育场1∶10模型试验,研究结构的静力性能和动力特性。深化设计阶段,通过介绍若干典型节点的细部构造,推广总结索膜节点的设计原则。研究结果表明:对宝安体育场而言,内外环均呈圆形且索膜形状一致的结构体型最优;A形柱可为整体结构提供有效侧向刚度,且沿索桁架方向对外环约束很小,是理想的外环支承;索桁架对外环施加集中力的同时对其提供侧向支承,因此外环一阶屈曲模态表现为以索桁架为侧向支点的失稳。Throughout the whole design process of the Shenzhen Bao＇ an Stadium, this paper presents a research into the major difficulties encountered during different stages of design. In the phase of conceptual design, comparison was made among 3 schemes from perspectives including architectural appearance, functionality, structural behavior and construction difficulties, etc. In the phase of scheme verification, both theoretical analysis and a 1 ： 10 scale model test were conducted in order to observe the static and dynamic performance of the structure. In the phase of detailed design, descriptions of several typical joints were presented and the basic principles for joint design of cable-membrane structures were summarized. The above research shows that for the Bao＇ an stadium, the spoke structure with circular inner and outer cable rings is the best choice. And A-shape column fits the spoke structure best, for its ability to provide sufficient lateral stiffness while making no constraint to the outer ring in radial direction. Research also shows, the 1 st buckling mode of the outer ring is in the form of buckling with cable trusses as fulcrums.
