摘要
高墩大跨预应力混凝土连续刚构桥梁采用悬臂法施工时,0号块作为基准节是施工的关键,而托架是0号块施工的承重受力结构,为其后续桥梁施工做准备。结合在建桥梁的工程实例,详细介绍托架的设计及理论计算。
No.0 block as the reference section is the key in the construction of high-pier long-span pre-stressed concrete continuous rigid-frame bridge by cantilever method. And the bracket is the load bearing stress structure of No.0 block construction, which is prepared for its following bridge construction.The article introduces the design and theoretical calculation of bracket by the engineering cases of bridge under construction in detail.
