摘　　要：摩洛哥布里格里格河谷斜拉桥是非洲目前最大跨度的钢-混凝土组合梁斜拉桥,上部结构采用混凝土主梁与钢横梁及混凝土预制桥面板的组合结构型式。文中介绍了主梁长大0号块施工采用悬臂吊架分次浇筑,主梁标准节段采用牵索挂篮施工边主梁,再利用桥面吊机安装钢横梁和预制桥面板,长合龙段采用牵索挂篮分为2次浇筑的施工方法。The cable-stayed bridge over Bouregreg River in Morocco is the largest span concrete steel composite bridge in Africa,using a combination form of concrete girder and steel cross beam precast concrete deck panels.During 0# block construction,the cantilever hanger is constructed separately.During cantilever segments construction,the guyed traveler is utilized for beam construction,and then the car crane is utilized for the installation of steel beams and precast deck panel.
