摘要
大跨度斜拉桥主塔设计高度较大,其大倾角斜塔柱的施工是难点及重点所在。本文以合福铁路铜陵长江大桥主塔施工为依托,重点介绍了其中塔柱施工时通过设置主动对顶横撑保证塔柱结构安全及线形的施工技术。
The design height of the main tower of large span cable-stayed bridge is large. The construction of the inclined pylon with large dip angle is the difficulty and key. Based on the construction of main tower in Fuzhou railway Tongling Yangtze River Bridge, this paper introduces the tower construction by setting the active opposite transverse bracing to ensure construction safety and alignment of the tower structure.
