摘要
重庆李渡长江大桥斜拉桥是一座采用镀锌平行钢丝体系斜拉索、双塔双索面、纵向弹性半漂浮体系的预应力混凝土边主梁斜拉桥。介绍该桥施工监控计算的计算方法、模型离散、斜拉索张拉索力的确定和挂篮立模标高的确定。
The cable-stayed bridge of Lidu Changjiang River Bridge in Chongqing is a prestressed concrete bridge designed as galvanized parallel steel wire stay cables, two pylons, double cable planes, longitudinal elastic semi-floating structural system and edge main girders. In this paper, the calculation for construction monitoring of the bridge is dealt with, in which the calculation methods, model discretion, stay cable tensioning force determination and form traveler set ting-up elevation are included.
