摘要: 结合菜园坝大桥工程实例,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。对成桥后的收缩徐变影响进行了专门考虑,增设附加预拱度,合拢后合拢误差小,桥面线形顺畅。

Abstract: The construction control of continuous rigid frame bridges which were constructed by the segmental cantilever method were studied in the light of engineering practice-Caiyuanba B Ramp Bridge, and the feasible control methods were proposed. Furthermore, influences on shrinkage and creep of the large-span bridge during its service was specially analyzed. An additional camber is considered and advised. The better connecting precision is reached, and the smooth linetype of the bridge can be formed.

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