摘要
钻孔灌注桩钢筋外露是一种较严重的病害,外露的钢筋极易锈蚀腐烂,导致桩基承载力下降,严重影响大桥的运行安全和使用寿命。根据新安大桥实例,分析了露筋产生的原因,提出了预防措施和处理方法。
Re-Bar exposure of the bored pile is a serious problem. Exposed Re-Bar can be easily corroded and rotted, thus resulting in the declination of the pile foundation's bearing capacity, and seriously affecting the safe operation of the bridge and service life. Based on examples of Xin'an Bridge, this paper will analyze the causes of Re-Bar exposure, and propose preventive measures and treatment methods.
