摘要
挂篮是目前大跨径预应力混凝土连续刚构桥和连续梁桥在悬臂浇注施工时主要采用的施工设备。挂篮变形的控制是连续刚构桥梁施工控制中的一项重要内容。结合工程实例,介绍挂篮预压荷载试验方法并分析试验中挂篮挠度的变化情况,对施工监控具有重要意义。
The hanging baskets are the main equipments in the cantilever casting construction of large-scale prestressed concrete continuous rigid bridge and continuous girder bridge. The distortion control of hanging basket is very important to the construction control of continuous rigid frame bridge. Combining with an engineering case, this paper introduces the pre-load test of the hanging basket and analyses the change of deflection of the hanging basket, which will be meaningful to construction monitoring.
