摘要
基于岳阳地区混凝土抗压强度和回弹值、声速值之间相关关系的试验研究,进行函数模型的拟和回归,建立了当地幂函数超声回弹综合法地方测强曲线,并验证它的优越性。同时论述混凝土强度和回弹值、声速值在几种因素影响下的相关关系。
On the basis of the experimental study of the relevant relation of the concrete compression strength,the rebounding value and the value of sound velocity of the areas of Yueyang,by carrying on the function plan and the regression of model,the author established the local stength detection curve of exponential function of the comprehensive method of ultrasonic and rebound and verify its superiority.At the same time,discussed the relevant relation between the intensity of concrete,the rebounding value and the value of sound velocity under the influence of several kinds of factors.
