摘要
基于汉江特大桥C50混凝土抗压强度和回弹值相关关系的研究,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与比较,建立了汉江特大桥回弹法检测混凝土强度专用测强曲线,探索出了快速简便地建立专用测强曲线的方法。
Based on the study on the relationship of compressive strength and rebound value of C50 concrete used in Hanjiang huge viaduct, 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 Hanjiang huge viaduct was founded, also, a rapid and simple way to establish special curve for measuring strength was founded.
