双线铁路单圆柱墩悬臂顶帽设计研究

摘要

以北尖篆河桥圆墩顶帽设计为例,通过介绍普通梁理论、深梁理论、牛腿法及公路规范中的撑杆—系杆体系,分别对圆墩顶帽进行了配筋设计比较,并通过ANSYS有限元程序对该结构进行了实体分析,指出其受力趋势,并对该结构的设计提出了建议。%Taking the circular cap design of Beijianzhuanhe Bridge as the case, it introduces common beam theory, deep beam theory, corbel method, and vault system in road norms, and compares the reinforcing design of circular pier cap. And then, it carries on data
