摘　　要：湛江吴川机场航站楼结构设计过程中重点解决以下问题:通过对大跨度、大悬臂屋盖的结构体系选型及内力分析,以满足建筑使用和结构受力,力求结构形式经济合理;采用预应力管桩基础和冲孔灌注桩基础结合形式,在满足不同荷载条件和受力要求的情况下提高经济指标。采取设计、材料及施工等层面有效措施,解决各单体结构超长、温度应力及混凝土收缩应力较大的问题,满足结构耐久性设计要求。对航站楼屋盖进行了基于大空间升温曲线的整体防火分析,得出大空间屋盖网架的防火规律。对布置不同位置的黏滞阻尼支座在风振分析下的效果进行评估,并对相关受力性能进行重点分析,保证节点受力性能,保障航站楼在强台风高发区的风振可靠性。In the structural design of Zhanjiang Wuchuan airport terminal, the following problems should be solved: In selecting the structural system of large-span and large-cantilever roofs, internal force analysis should be conducted. Under the safety of building use and structural force, the structural form should be economically reasonable. Prestressed pipe pile foundation and punched cast-in-place pile foundation are combined. It should try to save expense while meeting force requirements under different load conditions.Effective measures of design, materials selection, and construction should be taken to solve the problems in individual structures including overlength, high temperature stress and concrete shrinkage stress. Structural durability should also be satisfied in the design. By analyzing the fire resistance of the whole terminal roof based on the large space heating curve, the fireproof rule of large space roof grid structure should be obtained.The performance of different-position viscous camping bearings under wind-induced vibration should be evaluated. Some pertinent force analyses should also be taken specifically to assure the node performance.Therefore, it should guarantee the wind vibration reliability of the terminal in such an area of highly frequent strong typhoons.
