摘要
为研究高速公路某水库大桥C50混凝土抗压强度和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检验及比较,建立了某高速公路水库大桥专用测强曲线,得出了快速简便地建立专用测强曲线方法。
Based on the study on the relationship of compressive strength and rebound value of C50 concrete used in Highway Reservoir Bridge,by using computer to establish several kinds of mathematical models and comparing the average relative errors and relative standard deviation of the regression equation,a special curve for measuring concrete strength used in Highway Reservoir Bridge was founded,also,a rapid and simple way to establish special curve for measuring strength was founded.
