［摘要］第七屆世界軍運會主賽場主體結構采用鋼筋混凝土框架結構，屋蓋采用車輻式索承網格鋼結構，為了保證屋蓋結構受力安全合理，主體結構設計尤為重要。由于樁基持力層不同，需對基礎不均勻沉降進行分析，發(fā)現(xiàn)差異沉降過小可以忽略其對屋蓋和主體的影響。在進行主體結構設計時，重難點問題主要體現(xiàn)在屋蓋對主體結構的影響和超長結構的分析兩個方面。通過計算分析，屋蓋對主體的影響主要為支承屋蓋的框架柱和下一層相鄰跨梁板；超長結構溫度收縮問題可以通過合理考慮施工方案和采取有效措施，達到減小溫度應力和節(jié)約工期的目的。

Abstract:The main structure of the main stadium of seventh World Military Games adopted reinforced concrete frame structure, and its roof adopted cable supported lattice structure. In order to ensure the safety and rationality of the roof structure, the main structure design is particularly important. Because the bearing strata of pile foundation are different, it is necessary to analyze the uneven settlement of foundation. If the differential settlement is too small, the influence on roof and main structure could be neglected. The key and difficult problems of main structure design were mainly reflected in the influence of the roof on the main structure and the analysis of the super-long structure. Through calculation and analysis, the main influence of roof on the main structure is the frame column which supported the roof and the adjacent beam slab of the next floor. The analysis of super-long structure could be carried out through reasonable consideration of construction scheme and effective measures, which could reduce temperature stress, saving time and cost.
Keywords:World Military Games; main structure design; concrete frame structure; super-long structure; uneven settlement of foundation
