摘要
松花江桥主墩连续箱梁0#块采用钢管混凝土临时固结支墩和钢管支架组合结构法施工方案,解决了悬臂施工中不平衡荷载的不利影响,保证了结构稳定和安全。同时通过MIDAS程序建立模型进行钢管支架设计并进行强度、刚度和稳定性检算,并对支架预压进行了详细介绍。
Steel pipe concrete temporary construction pier and steel pipe support construction plan used in 0# of main pier continuous box beam in Songhuajiang River Bridge solves the problems caused by unbalanced load in cantilever construc-tion, and guarantees the structure safety and stableness. By model established through MIDAS procedure is used to design the steel pipes support, check their intensity, rigidity, and stability, and explain in detail the support pre-compression.
