摘　　要：文中介绍宜昌附近山区新建高速薄壁空心墩、双肢薄壁空心墩、145米跨连续刚构桥施工案例,针对不同结构的超高墩身采用不同托架和反力架压载方式解决0号段施工,使用菱形挂篮完成悬臂梁施工,同时介绍了主要施工工艺和部分控制参数,为类似的桥梁工程提供了一定的参考。This article introduces the construction cases of newly built high-speed thin-walled hollow piers,double leg thin-walled hollow piers,and 145 meters span continuous rigid frame bridges in the mountainous areas near Yichang.Different brackets and reaction frames are used to load the ultra-high pier bodies of different structures to solve the construction of Section 0,and diamond shaped hanging baskets are used to complete the construction of cantilever beams.At the same time,the main construction technology and some control parameters are introduced,providing some reference for similar bridge projects.
