钢筋混凝土连续板桥裂缝分析

钢筋混凝土连续板在桥梁施工阶段产生裂缝的原因很多。在对一座跨线桥钢筋混凝土连续板裂缝现场检查的基础上，根据桥梁结构理论方法进行了分析计算，并且认为对于现浇的钢筋混凝土连续板，在设计上应对施工阶段进行详细计算并不宜采用束筋；建议在施工上应注意空心板底的泄水孔布置与通畅，预留孔道不宜采用充气胶囊。

Analysis of Cause of Cracks on Reinforced Concrete Continuous Slab Bridge

Many causes can lead to cracks on the reinforced concrete continuous slab bridges in the period of construction By means of the survey of the cracks on a certain reinforced concrete continuous slab bridge, its causes are analyzed and studied based on the theories of bridge structure It is better not to use the bounded steels in design for the cast in place reinforced concrete continuous slab. The suggests that the disposal of drainage should be paid attention to and the drainage kept to work well in the process of construction are put forward also in this paper.
