跨铁路特大桥防护棚架设计及结构验算

Design and Structural Checking of Protective Scaffolding for Railway-Crossing Extra-Large Bridge

为保证上跨施工过程中让高速列车在其下方安全通过,汾河特大桥采用了防护棚架的设计方案。以汾河特大桥连续刚构施工防护棚架设计为例,重点介绍了防护棚架结构稳定性验算过程。结果表明,防护棚架在竖向荷载作用下结构是安全的。

For ensuring the safe traveling of high-speed train in the construction process of overpassing construction, Fenhe River Extra-Large Bridge used the design plan of protective scaffolding. Taking the design of protective scaffolding in continuous rigid frame construction of Fenhe River extra-large bridge as an example, the paper focuses on the structural stability of the protective scaffolding checking process. The results show that protective scaffolding structure under the function of vertical load is safe.
