摘要
宁安铁路安庆长江大桥主塔下塔柱截面尺寸大,倾斜角度大,塔柱施工采用了改进的液压自爬模系统,通过计算分析并优化方案工艺,满足了塔柱6m大节段施工的要求。重点介绍该桥倾斜塔柱液压自爬模大节段施工计算分析及应用。
The sectional dimention and tilt angle of the lower pylon in Anqing Changjiang River RailwayBridge is very large. The construction of lower pylon adopts modified hydraulic self - climbing formwork. According to Calculation, analysis and optimization of process, The formwork met the requirement to construction of 6m Large pylon segment. Calculation, analysis and application to construction of large pylon segment by hydraulic self - climbing formwork is stressed introduced.
