摘要
随着连续刚构桥施工技术的不断进步,悬臂浇筑成为在实际工程中使用最为广泛的一种连续刚构桥施工方法。在悬臂施工过程中,由于桥梁结构存在由静定结构转变为超静定结构的过程,因此在施工过程中要注意对桥梁线型、内力、预拱度以及挠度等因素进行施工过程监控,以满足桥梁结构的要求。
In recent years, with the continuous progress of the construction technology of continuous rigid frame bridge, cantilever pouring are widely used in practical engineering as a continuous rigid frame bridge construction method. There is a process for bridge structure to change from static structure to hyperstatic struc-ture in the process of the cantilever construction. Therefore, attention should be paid to the bridge linear, in-ternal forces, camber and deflection factors during the construction in order to meet the requirements of the bridge structure.
