大跨径悬浇拱桥设计与施工

Design and Construction of Long-span Arch Bridge by Cast-in-place Cantilever Method

悬臂浇筑法克服了传统拱桥施工方法的一些缺点,因此在大跨径钢筋混凝土拱桥施工中越来越受到重视,但目前国内在这方面尚处于起步和探索阶段,实际工程应用非常有限。文中以木蓬特大桥为背景,从结构设计、施工方法、受力计算及施工注意事项等方面进行了介绍,为采用悬臂浇筑法施工的大跨径钢筋混凝土拱桥研究提供参考。

Cast-in-place cantilever method overcomes some shortcomings of traditional arch bridge construction method and attracts more and more attention in long-span reinforced concrete arch bridge construction.However,domestic work in the filed is still in the initial stage and its application in civil engineering is rather limited.Based on the background of Mupeng Bridge,the paper introduced in detail the structural design,construction method,stress calculation and the points for attention for construction,which provides references to the researchers engaged in long-span reinforced concrete arch bridges constructed by cast-in-place cantilever method.
