Abstract

Abstract: The construction control of continuous rigid frame bridges by the segmental cantilever method is studied in the light of engineering practice of Xiaoanxi bridge，and the feasible control methods are proposed.Futhermore，the influence of shrinkage and creep on the large-span bridge during its service is specially an alyzed.An additional camber with shrinkage and creep is counted in.The better connecting precision is acquired，the smoother line-type of the bridge is formed.

Key words: continuous rigid frame, construction control, shrinkage and creep

摘要： 结合小安溪大桥工程实例，对采用分节段悬臂浇筑施工的连续刚构桥梁结构施工控制进行了研究，提出了切实可行的控制方法.专门考虑了成桥后的收缩徐变影响，增设附加预拱度，合拢后合拢误差小，桥面线形顺畅.

关键词: 连续刚构, 施工控制, 收缩徐变
