摘　　要：某市政景观大桥跨越地质软弱的冲沟,桥梁顶部离地高度达48m,上构大尺寸、超重拱肋节段构件的吊装施工困难。本项目通过搭设施工钢便桥,科学制订拱肋的吊装方案,并周密组织施工。顺利、安全完成了拱肋构件的高空吊装作业。A municipal landscape bridge crosses a gully with weak geology.The height of the top of the bridge is up to 48m from the ground.It is difficult to hoist the large-size and overweight arch rib segments of the superstructure.In this project,through the construction of industrial steel temporary bridges,the hoisting plan of the arch ribs is scientifically formulated,and the construction is organized carefully.The high-altitude hoisting operation of the arch rib components was completed smoothly and safely.
