软土地基满堂支架现浇梁施工质量控制

Construction of Cast-in-situ Continuous Box Girder on the Soft Foundation

介绍了临洪河特大桥软土地基满堂支架现浇梁施工工艺,结合箱梁二次浇筑的特点,通过施工过程中采取合适的控制措施,有效防止了墩顶负弯矩区域箱梁裂缝的产生。

This paper describes the provisional ben bridge soft-situ beam bracket packed with how to ensure the quality of construction-related control measures. As well as the box girder with the charac- teristics of the second casting, through the construction process take appropriate control measures, effectively prevent the negative moment region of the pier top box girder cracks.
