摘要
老集高速公路位于高寒干旱的内蒙古地区。针对该区域内钢筋混凝土简支箱梁翼板缘出现裂缝的现象进行了分析。通过分析得出该类型裂缝产生的主要原因主要在于混凝土收缩徐变,温差等结构变形,在此基础上提出了有效预防和处理钢筋混凝土简支箱梁翼板缘裂缝的相关措施。
Laoju highway is located in the cold and dry region in Inner Mongolia. For the above region, the phenomenon of the reinforced concrete box girder flange edge cracks are analyzed. Through analyzing, it is concluded that the main causes of this type of crack are the structural deformation as concrete shrinkage and creep, the temperature deformation, etc. The proposed and related measures effective prevention and treatment of reinforced concrete box girder flange edge of crack are suggested.
