回弹法检测混凝土剪力墙与顶板的探讨

The Application of Rebound Method in the Test of Reinforced Concrete Shear Wall and Roof

基于对现行规范和相关资料的学习和认识,以及大量回弹法检测混凝土强度的实测数据,发现在用中型回弹仪检测混凝土剪力墙和顶板时,两者的强度指标存在差异。通过对功能关系的分析,得出检测的剪力墙的混凝土强度高于混凝土顶板,且剪力墙强度平均相对误差与标准差都小于顶板;通过现场采集数据,并绘制成折线图,可以直观的发现检测的剪力墙强度高于顶板强度,且剪力墙强度的离散性好于顶板的。

We conclude that there are some differences in the strength index between the concrete shear wall and the concrete roof based on studying and understanding of existing norms and relevant information and a large measured data of rebound testing concrete strength.On one hand,we know that the strength of concrete shear walls is higher than the concrete roof and the average relative error and standard deviation is also less than the roof through the analysis of functional relationships.On the other hand,by collecting data through field then drawing it to line,it can be found in the intuitive the strength of shear is higher than the roof and the shear is better than the roof in discrete of strength.
