阳茂高速特大桥连续梁施工技术研究

Research on Construction Technology of Continuous Beam of Yang-Mao Expressway Bridge

随着我国高速铁路建设的飞速发展,高速铁路大跨度桥梁的施工技术受到更为广泛的关注。本文结合新建深圳至茂名铁路高速特大桥工程实例,阐述了阳茂高速铁路特大桥挂篮悬臂浇筑施工过程的施工工艺操作要点及方法,并着重对江门至茂名段(76+160+76)m连续梁挂篮悬臂浇筑工法、及合拢段技术进行了论述与研究。

With the rapid development of China＇s high-speed railway construction, high-speed railway long-span bridge construction technology has been more extensive attention. Taking a new high-speed railway from Shenzhen to Mao-ming Bridge project as an example,this paper expounds the construction technology operation points and methods of the cantilever casting construction process of Yang-Mao High Speed Railway Bridge, focuses on the discuss and analysis of hanging basket cantilever casting method and linear control technology of Jiang-men to Mao-ming section（76 ＋160 ＋76） m continuous beam and provides information and reference for the similar bridge construction.
