摘　　要：挂篮悬臂现浇法施工是现浇连续梁施工工艺中较为成熟的一种施工方法,通过挂篮的结构设计以及挂篮悬臂施工两方面,从挂篮构造、挂篮受力分析、挂篮安装、预压、移动、拆除等各个工艺环节进行详细介绍,提出了挂篮结构设计的重点为荷载组合,结构受力重点部位为底平台系统,而后通过对挂篮预压观测数据进行拟合,得出荷载-变形曲线回归方程,指导连续箱梁线形控制。The hanging basket cantilever cast-in-place method is a relatively mature construction method in the construction process of cast-in-place continuous beams.Through the structural design of the hanging basket and the cantilever construction of the hanging basket,this article provides a detailed introduction to various process links such as hanging basket structure,hanging basket stress analysis,hanging basket installation,preloading,movement,and demolition.It proposes that the focus of hanging basket structure design is load combination,and the key part of structural stress is the bottom platform system.Then,by fitting the pre compression observation data of the hanging basket,a regression equation of the load deformation curve was obtained to guide the linear control of the continuous box girder.
