摘　　要：提出一种新的模糊回归数据融合方法的超声回弹测强曲线,此测强曲线可以减小偶然误差,提高检测的精度。同时,运用置信检验理论提出了在给定置信度下经过修正后的建筑结构强度的置信区间,并给出了混凝土强度的三个评定标准。此方法比较符合工程实际情况,且对混凝土强度做出了定量的判定。A new ultrasonic-rebound curve of fuzzy regression and data fusion method is presented for evaluating concrete strength in this paper. The ultrasonic-rebound curve can reduce the accidental error, and thus increase the precision of concrete strength measurements. Meanwhile, the modified confidential interval of concrete structure strength under the given confidence level is obtained by using the confidence test theory, and three evaluation standards of the concrete structure strength are given. This method is roughly consistent with that of actual engineering, and it makes quantitative judgment of the concrete structure strength.
