［摘要］鄂尔多斯东胜区植物园温室屋盖结构采用大跨度空间结构，其屋盖曲面为有中心筒支撑的自由曲面。针对温室结构特点，在研究了国内外典型温室结构的基础上，对适用本项目的结构形式进行了研究。对单层、双层结构体系受力性能进行了对比，并结合建筑造型采用了单层空间结构体系；由于施工难度较大，针对钢结构、铝合金结构分别进行了结构受力性能、节点构造、施工难度、施工速度以及建造与使用成本等方面的对比研究，最终选用了铝合金结构；对ETFE气枕结构与玻璃屋面进行了技术经济性对比，最终确定采用玻璃屋面。最后对屋盖结构的设计情况进行了介绍。

Abstract:Large span space structure is adopted in the greenhouse roof structure of botanical garden in Erdos Dongsheng District. Free form surface is used in the roof modeling. Considering the special feature of the greenhouse, and based on the analysis of some domestic and overseas representative structures, the structure style which is suitable for the greenhouse in Erdos Dongsheng District was studied. Mechanical behavior comparison between the single\|layer structure system and double\|layer structure system was performed, and the single layer roof structure system is finally adopted. Considering the construction difficulty, various comparisons between the steel structure and aluminum structure were performed, such as the comparisons on the mechanical behavior, joint construction, construction difficulty, construction speed and economical efficiency. Based on the results of the comparisons, aluminum structure is adopted for the greenhouse. Techniqueeconomics comparisons were also performed between the ETFE cushion and glass roof, and glass roof is finally adopted. Design on the roof structure was introduced.

Keywords:greenhouse structure； single layer space structure； steel structure； aluminum structure； ETFE cushion； glass roof
