| 摘 要： | 钢筋混凝土桥墩墩身非受力裂缝是目前施工中经常发生的现象,其产生原因总结为混凝土自身的体积变化受到内部约束时产生的拉应力超过了混凝土轴心抗拉能力。本文针对墩身裂缝的成因、防治及修补方法进行简要分析,对以后施工中出现类似问题有一定的借鉴意义。

| Abstract: | Shafts of the stress fracture is often happened in the current construction phenomenon, the causes of the stress crack are summed up in the volume of concrete itself changes caused by internal constraints of axial tensile stress more than concrete tensile ability. On the causes of cracks and the shafts of the prevention and control, and repair method is briefly analyzed in this article, which has certain reference significance for future similar problems in the construction. |
