摘　　要：近年来我国绿道建设发展迅速,结合云南怒江美丽公路绿道建设项目独特的地形、地貌、地质、水文、线路特点以及当地的施工技术水平,提出了绿道常规桥梁的四种基本结构形式:钢-混组合梁、钢结构Π梁、挡墙外侧悬挑钢架结构、挡墙外侧立柱钢架结构。为了探究这四种常规桥梁在绿道建设中的适用范围,综合怒江美丽公路项目的应用情况和山区绿道线路特点,分别详细介绍了其结构布置特点、结构体系特点、结构关键技术,从工程实际出发,结合受力性能、实际施工、桥型特点、经济性、耐久性、舒适性等提出了四种桥型各自的布置特点和适用范围,并深入分析了各桥型在绿道建设中的关键技术,以促进我国绿道建设事业发展,为山区绿道人行桥建设提供了参考和借鉴。In recent years,greenway construction in China has developed rapidly.Combined with the unique topography,landform,geology,hydrology and route characteristics of the greenway construction project of Meili Highway in Nujiang,Yunnan Province,the conventional greenway bridge adopts four types of bridge types,including steel-concrete composite beams,steel structure∏beams,steel suspension structure outside the retaining wall and steel frame structure outside the retaining wall.In order to explore the applicability of these four types of conventional greenway Bridges,based on the application situation of Nujiang Meili Highway project and the characteristics of greenway routes in mountainous areas,the characteristics of their structural layout,structural system and key technologies are introduced.Based on the engineering practice,the respective application ranges of these four types of Bridges are proposed in combination with mechanical performance,actual construction,bridge type characteristics,economy,durability and comfort.The key technologies are analyzed in order to promote the development of greenway construction in our country and provide reference for the construction of greenway pedestrian bridge in mountainous areas.
