摘　　要：车辐式张拉结构造型轻盈通透,常作为大跨度体育场建筑的屋盖结构形式。对于由索杆组成的车辐式张拉屋盖结构而言,屋盖施工常常采用整体张拉成型的方法,其张拉方案的制定以及张拉过程中"力"与"形"的控制是施工张拉过程的核心内容。分析制定张拉方案所应当遵循的原则,并以深圳宝安体育场屋盖结构为例,对拟制定的3种张拉方案进行张拉过程数值模拟分析,同时依据数值分析结果评估各种张拉方案的优缺点。Wheel tension structure, as a roof of a stadium, is widely used around the world. During full construction process of wheel tension structure, the control and verification of structural configurations and corresponding internal force distributions during the tension process of whole roof was focused generally by designers, because both structural configurations and internal forces for such a tension structure are strongly depended on each other. Accordingly, the basic principles for detennining the best tension scheme and simulation tension process of tension structure are presented in this paper. Finally, as a typical example, the three available tension schemes of roof tension structure of Baoan Stadium in Shenzhen are carefully made, and corresponding simulation tension analysis for these three tension schemes are completed for finding the best tension scheme in the engineering construction.
