摘　　要：我国在大型机场的设计方面已经取得了较丰富的经验,但将小型机场做小做精、体现地方特色方面稍显不足。因此,文中以四川省宜宾市新机场工程为例,对宜宾新机场的工程概况、结构体系进行介绍,并对结构设计中超长混凝土、超长钢结构、抗连续倒塌等问题进行了分析,提出了解决措施。研究发现,设置伸缩缝、后浇带、加强构件腰筋等措施可以有效控制超长混凝土收缩和温度应力;设置弹簧支座可以降低温度对钢屋面的影响,并对屋顶有效隔震,可为类似小型机场建设提供参考。China has accumulated amounts of experience in designing large-scale airports, nevertheless it is not enough to construct small airports which show characteristics of local culture effectively. Taking the new airport of Yibin, Sichuan Province as an example, the project overview and structure system were introduced in this study. And the structural designing about the super-long concrete structure, super-long steel structure and the resistance of the progressive collapse were analyzed and solutions were proposed. The results show that the setting of the expansion joint, the post-cast strip, and strengthening the waist muscle can effectively control the shrinkage and temperature stress of ultra-long concrete. and the elastic support can reduce the effect induced by temperature in super-long steel structures and absorb the energy induced by the earthquake.
