摘要
造成钢管混凝土拱桥的拱肋脱空的原因有很多,轴向压力、温度变化、施工方法、法拉盘和加筋环的设计、混凝土配合比和混凝土的收缩徐变等原因都有可能造成拱肋脱空,应从多方面进行总结和分析。
Concrete arch ribs separation are caused by many reasons, such as the axial pressure, temperature changes, construction method, farah plate and reinforced ring design, concrete mix and concrete shrinkage and creep are all the possible causes of rib separation. We should summarize and analyze it in many aspects.
