回弹法检测混凝土强度专用测强曲线的建立与应用

Establishment and Application of the Special Measuring Curve to Detect the Concrete Strength with the Rebound Method

为研究某高架桥C 50混凝土抗压强度与回弹值之间的相互关系,应用计算机进行了多种数学模型的拟合回归,对多种回归方程的平均相对误差和相对标准差进行了检验与比较,建立了该高架桥专用测强曲线,得出了快速简便地建立专用测强曲线的方法。

In order to make sure of the relationship between the compressive strength and the rebound value of C 50 concrete used in certain viaduct, the fitting regression of several kinds of mathematical models has been made with the computer, the average relative errors and relative standard deviation of the regression equation tested and compared, and as a result, a special curve for measuring the strength of the concrete used in this viaduct established, and a rapid and simple way to build the special curve for strength measurement founded.
