桥梁结构混凝土裂缝产生的原因及预防处理对策

从混凝土内部结构性能、外荷载、外部环境、混凝土收缩、材料质量及配合比、钢筋锈蚀等几个方面对桥梁混凝土裂缝产生的内因、外因、类型、部位进行分析和总结,并从设计、施工控制方面对桥梁混凝土裂缝的预防处理措施进行了阐述。最后介绍了几种桥梁结构裂缝常用的处理方法,供工程实践借鉴。

Reasons and Treatments for Cracks in Bridge Construction Concrete

This text starts construction from the inner structure performance,outside benelux carry from the structure concrete,external environment,concrete shrink and material the mass and team work compare,reinforcing bar rust eclipse etc.a few aspects us bridge concrete tears generate of inside because of,outside because of,the type,part carry on analysis and summary,and from design,construction control aspect us prevention bridge concrete tears of measure,handle should the question progress noting elaborate.Finally introduced a few bridge structure tears in common use treatment,was provided for engineering to practice to draw lessons from,in order to in the design and the construction effectively control tears of creation,raise the bridge concrete construction mass,ensure bridge mass safety.
