摘要
基于某工程混凝土抗压强度和回弹值相关关系的试验研究,进行了多种数学函数模型的拟合回归和精度、误差等回归方程效果的检验及比较,建立了在建工程幂函数回弹法专用测强曲线,并证明它的优越性。
On the basic of the experimental study of the relevant relation of the intensity of concrete and rebound value of the constructing proJect, carry on the test and comparison of the results of regression equation of various kinds of the regression of function models and precision and the orror, etc.The local curve for measuring strength of the regression method of exponential function is established and proved its superiority.
