摘　　要：机场高架桥作为航站楼内外交通联络的基础配套设施,是机场交通枢纽中的重要组成,其设计需充分考虑与地面道路、航站楼及地铁车站等重要工程的空间衔接,并结合现场复杂地形地质条件合理选择桥梁结构形式。以某大型机场改扩建工程为研究背景,重点对机场改扩建工程区间高架桥工程设计要点进行探究,通过对高架桥设计中上下部结构形式从受力、施工工艺、景观效果及经济指标等方面进行综合比较分析,并结合现状场地特点确定符合该工程的机场高架桥梁形式。针对桥梁与地铁车站共建、航站楼衔接及新旧桥拼接异形桥等特殊节点处桥梁设计进行重难点研究,最终确定符合该工程的合理设计方案,研究成果为类似工程的设计提供一定的借鉴价值。The airport elevated bridge,as a basic supporting facility for the transportation connection inside and outside the terminal building,is an important component of the airport transportation hub.The design should fully consider the spatial connection with important projects such as ground roads,terminal buildings,and subway stations,and reasonably select the bridge structure form based on the complex terrain and geological conditions on site.This article takes a large airport renovation and expansion project as the research background,focusing on exploring the design points of the elevated bridge project in the airport renovation and expansion project section.Through comprehensive comparative analysis of the upper and lower structural types in the elevated bridge design from the aspects of stress,construction technology,landscape effect,and economic indicators,and combined with the current site characteristics,the airport elevated bridge type that meets the requirements of this project is determined.A study was conducted on the key and difficult points of bridge design at special nodes such as the joint construction of bridges and subway stations,the connection between terminal buildings,and the splicing of new and old bridges with irregular shapes.The final design plan that meets the requirements of this project was determined,and the research results provide certain reference value for the design of similar projects.
