对桥梁桩基础中出现的断桩现象进行分析,从导管、水泥混凝土质量、施工过程中的卡管、埋管、钢筋笼上浮等方面介绍了预防和改进措施,并对断桩无法补救的现象进行重新浇筑或者补桩处理,为以后实践应用提供了技术基础。

This paper analyzes the phenomenon of broken piles in bridge pile foundations. Factors affecting the broken piles of bridge pile foundations,ducts,cement concrete quality,stuck pipes during construction,buried pipes,and floating reinforcement cages have all been taken to prevent and improve the measures.
