| 摘 要： | 国家体育场看台共分三层，通过环梁将混凝土结构柱、钢管混凝土柱和上层看台斜梁连接在一起。形成上层看台结构体系，环梁随斜梁端头起伏呈马鞍形。由于看台结构层层外挑，环梁支撑、定位、配模施工难度很大，对此采取针对性措施，快速精确地完成了该空间环梁的施工。

| Abstract: | The stand of National Stadium is divided into three tiers. Concrete structural column, steel tube concrete column and sloping beam on the top tier are connected together to form the structural system of upper stand, and the saddle-shaped ring beam stretches along fluctuation of the sloping beam ends. The stand adopts cantilever structure tier by tier, so it is very difficult to support, locate and match template for the ring beam. Special measures are adopted to guarantee fast and accurate construction of the space ring beam. |
