摘　　要：悬臂浇筑的连续梁(刚构)桥施工中须设置施工预拱度,该预拱度的设置有多种影响因素。通过分析与实例计算结果表明,这些影响因素中容易被计算者忽视的施工阶段划分方式恰恰是对施工预拱度的设置具有决定作用的因素。Construction precamber must be set in the construction of cantilevered casting continuous beam(rigid frame)bridge,and the setting of precamber has many influence factors.The analysis and example calculation results show that among these influencing factors,the construction stage division method,which is easily overlooked by the calculator,is the decisive factor for the setting of the construction precamber.

关 键 词：悬臂施工 预拱度设置 施工阶段划分
