(40+56+40)m铁路连续箱梁桥满堂支架设计

The design of full support for cast in place continuous box bridge for spans of (40+56+40)m

结合某(40+56+40)m铁路连续箱梁桥的施工实例,从支架的稳定性、纵横木的强度、刚度以及地基承载力三个方面对碗扣型满堂支架进行了设计及验算,并对支架搭设要点进行了总结,对现浇箱梁的施工有一定的参考价值。

On the basis of constrution example of some cast in place railway continuous box girder bridge for spans of （40 ＋ 56 ＋ 40）m, the design and check for full support were performed considering for the stability of full support, the strength and stiffness for longgitudinal and later3 timber, the capacity for subgrade. At the same time the dificulty of construction for full support sums up. It will have some reference value fo1 construction of cast in place continuous box girder.
