摘要
斜拉悬臂浇筑法是国外大跨径钢筋混凝土拱桥常用的施工方法之一。该方法由临时斜拉索扣住悬臂半拱,逐渐地向拱顶现浇拱肋节段,直至全桥合拢。以国外几座采用斜拉悬浇施工法施工的拱桥为例,介绍了施工过程及施工控制中的关键问题,为该方法在国内的广泛应用提供经验及参考。
Cable stayed cast-in-place cantilever construction method is one of the main construction methods for long span reinforced concrete arch bridges.The main process of this method include half an arch was withhold by temporary stay cables,arch rib segment was casted along the direction of the top of arch gradually still closure of the whole bridge.Several abroad bridges constructed by cable stayed cast-in-place cantilever method were selected as examples,the key problems in construction process and construction control in order to provide experience and conference for application of this construction in China.
