摘要
九江长江公路大桥主桥混凝土箱梁为整体式超宽带肋单箱三室截面,采用大直径钢管支架现浇方案。为确保支架结构安全,从支架方案基础方案、钢管支架结构方案及分配梁系统三个关键地方进行方案设计研究。结果证明方案安全,可以为类似工程提供良好的借鉴。
Jiujiang Yangtze River Highway Bridge concrete box girder used ultra-wide single box 3-room with rib cross-section.The construction program is large diameter steel pipe stent cast-in-place program.To ensure the structural safety of the stent,Bracket for base programs and programs and distribution of steel support structure beam system three key areas detailed design studies.The construction results prove program safety,can provide a good reference for similar projects.
