摘 要: 利用回弹法在实验室测定的江门市区的混凝土抗压强度和标准试验抗压强度的有关数据,经回归统计分析建立了回弹法专用测强曲线,并对该曲线的置信度、精确度进行了分析研究. 结果表明该曲线精度高,置信度良好,可以直接应用于测定工程实际中的混凝土构件或结构的强度. In laboratory, a group dates of both the compression strength and the correlative resilience of 42 kinds of concrete are obtained experimentally. The rating curve of the compression strength against the resilience of the concrete are then determined by means of regression analysis. And the accuracy and the probability of the regression are analyzed and discussed. The results show that the rating curve established in this study can be applied to resilience method for determining the compression strength of the concrete in engineering structures.
