| 摘 要： | 提出一种建筑结构强度无损检测区间评定方法,此方法能较好地反映工程的实际情况.该方法运用逆回归模型和置信检验理论给出了在一定置信度下的建筑结构混凝土强度的置信上、下限和置信区间,并给出了混凝土强度的合格和不合格判定标准,从而形成了逆回归回弹法检测建筑结构混凝土强度的新体系.通过工程实例证明,本文提出的方法比传统的利用回归模型和点估计方法判断混凝土强度更符合工程实际,且能对混凝土强度做出定量化的判断.

| Abstract: | An interval assessing method of nondestructive testing of structure strength is described in this paper, which could more accurately present the practice condition. Meanwhile, the lower and upper confidence limits, the confidence intervals are given by using the confidence test theory and inverse regression, and the evaluation standards of concrete strength are given. Therefore, a new rebound system of inverse regression for testing concrete strength is obtained. Through practical examples, this method more accords with the engineering practice than that of the traditional methods by using traditional regression and point estimation, and it provides quantitative judgment of concrete strength. |
