廊坊市混凝土实体回弹法测强曲线分析与验证

Experimental Research on Rebound Curve Fitting for the Real Situation of Concretes in Langfang

对廊坊地区的实体结构混凝土构件采用回弹法测强,利用获取的多组平均回弹值、碳化深度值和芯样抗压强度值等数据进行回归分析得到廊坊地区回弹测强曲线,该曲线能真正反映廊坊市结构实体的混凝土强度,为混凝土结构检测验收打下坚实的基础。

During the process of this research, the curve is not assumed under the mode of experimental modal. Instead, we measure the strength based on the real structural concretes, With all these data, necessary assumptions and calculations, we get the regional strength curve for Lang fang region. Analysis of the data and the experimental results reflect that this curve can better reflect the real situation of concretes compressive strenzth, which lays a stron~ foundation for acceotance of concrete structure.
