摘要
造成桥梁工程出现裂缝的原因很多,而且产生的原因较为复杂,常见的原因有收缩裂缝、温差裂缝,这两种原因都是与混凝土材料的特性有关。采用嵌缝封堵法,灌浆,表面修补法,电化学防护法以及加固封闭法都是有效的修补处理方法,其中表面修补法主要是针对一些不会影响桥梁结构承载力及稳定性的表面缝隙,不仅简单、有效,与其他方法比较其施工的成本最低。
There are many causes which make the cracks in bridge construction, and the causes are always complex. Such as shrinkage crack and temperature difference crack, these two are related to the characteristics of concrete materials. The caulking blocking method, grouting, surface repair electrochemical protection and reinforcement sealing method are all effective repairing methods. And among these methods, the surface repair mainly focuses on the surface cracks which have no effects on the bearing capacity and stability of bridge structure, and it is simple and effective, and it has the lowest cost compared with other processing methods.
