摘要
结合浙赣铁路大圆里特大桥主跨悬臂浇筑的施工状况,重点阐述采用挂篮悬臂浇筑施工中结构预拱度设置的方法、影响挠度控制的一些主要因素,从而确定结构合拢精度和成桥后的线型。
Upon the idiographic construction conditions of main-span cantilever casting on Da Yuanli super bridge ,Zhejiang-jiangxi Railway,this thesis mainly illustrates the setting method of the structural predetermined camber in the process of basket cantilever construction and some key factors which influence the control of deflection so as to ensure structure fold accurancy and linearity of the finished bridge.
