城市大悬臂鱼腹式现浇箱梁桥设计

Design of Urban Large-Cantilever Fish-Belly Cast-in-place Box Girder Bridge

本文通过对某工程实例研究分析,介绍了城市大悬臂鱼腹式连续箱梁桥的结构设计和构造特点,并结合纵、横向配束,进行结构纵向受力分析和横梁横向受力分析,较详细地说明了此箱梁的结构设计要点,为以后同类型城市大悬臂鱼腹式现浇箱梁桥的设计提供参考。

Through the study and analysis of a project case,this paper introduces the structural design and structural characteristics of urban large-cantilever fish-belly continuous box girder bridge,and combines the longitudinal and transverse bundles to carry out the structural longitudinal force analysis and transverse beam transverse force analysis,and explains the key points of structural design of box girder in detail,which provides a reference for the design of same type of urban large-cantilever fish-belly cast-in-place box girder bridge in the future.
