摘要
结合张家跨线桥连续梁的施工，着重阐述了采用挂篮悬臂灌注施工过程中产生挠度的一些因素、设置预拱度以及进行线形控制的有效措施，以期确保合拢精度。
By taking construction of continuous girder of Zhangjia overpass bridge as an example some factors of producing deflection in the process of cantilever casting ,setting prearch and efficent methods of alignment control are specially introduced,so that to guarantee the accuracy of closure.
