摘　　要：研究发现采用传统回弹法测强曲线的自变量与因变量的选取存在问题,造成误差较大,且有时不符合工程要求,为此提出了一种测强曲线的逆向回归模型,将原模型中自变量与因变量对换,使试验数据处理更符合回归分析理论,并对220组试验数据分析得出其平均相对误差和相对标准差比传统回归模型明显偏小,从而使回弹法检测混凝土强度的结果更加准确、可靠。Study showed that the traditional strength curve of rebound method has the problem of variable select, which leads to a rather large error,and inconsistent with project requirement. Therefore in this paper we present a kind of inverse regression model of strong curve, independent and dependent variable of original model in exchange, which makes data handling agree with regression analysis theory. Testing 220 groups of detection data analysis makes its average relative error and standard deviation lower, and the result of rebound method tests concrete strength more accurate,reliable than ever.
