摘　　要：结合西部大通道包(头)北(海)线陕西境黄陵至延安段老庄河特大桥在施工监控中的实践,对大跨径连续刚构桥悬臂施工的线形进行控制,主要是对变形预抛值与桥面铺装拟合方法进行研究,并结合实测数据总结出变形预抛值的最佳设置方法及桥面铺装拟合曲线的理论方法。In combination with the practice in construction supervision of Laozhuanghe Super Large Bridge from Huangling to Yan＇ an in Shannxi Province of the western passageway Baotou--Beihai, this paper carries on the control for the line shape of cantilever construction of the large span continuous rigid bridge, focusing on the research on fitting method between the deformation precast value and the deck pavement. Based on the measured data, the paper summarizes the optimal setting method for deformation precast value and the theoretical method for fitting curve of deck pavement.
