摘要
对某钢管混凝土十字交叉吊杆拱桥支座更换顶升方案进行分析研究,采用有限元软件分析并探讨主梁与梯道梁相接处的钢板连接、主梁与主拱相交处的橡胶圈、单点顶升与多点顶升、顶升位置、附加支撑以及顶升最大高度对拱梁受力性能的影响,得出相应结论及建议,为同类型桥梁施工提供借鉴。
This paper analyzes and researches jacking plans for replacement of supports of some steel tube concrete crossing suspender arch bridge,employs finite element software to analyze and probe into influences of connection of steel plates at joint between girder and stairway beam,rubber rings at the crossing between girder and main arch,single-point jacking and multi-point jacking,jacking position,additional supports and the max.jacking height on stressed performance of arched beams and obtains corresponding conclusions and suggestions,providing a reference for construction of bridges of the same type.
