摘　　要：介绍了连续刚构桥在利用挂篮方法施工0号块附近悬浇段时,由于空间有限,内滑梁系统不能正常前移的解决思路与施工方法。通过改变固定和滑动悬吊框在内滑梁系统中相对位置,实现了挂篮内滑梁系统在空间受限条件下的正常前移,使挂篮在连续梁施工中的便利性和安全性得以充分体现。In the paper,a practical construction method is brought to handle the problem that because the limited space,the inner sliding beam system can't move normally when the hanging form traveler is used to construct segments near the O#block of the continuous rigid frame bridge.In this method,by changing the relative positions of the fixed and sliding suspension frames,even though the space is limited,the normal moving of the inner sliding beam system of the hanging form traveler can be achieved,which makes convenience and safety characteristics of the hanging form traveler become more obvious in the continuous beam construction.
