摘　　要：混凝土强度现场检测结果的准确性直接关系到结构的安全性。笔者利用通用回弹测强曲线提供的共性信息和现场试验得到的个性信息 ,通过数据融合方法 ,提出适应于现场情况的混凝土强度与回弹值之间的关系曲线。该曲线仍运用原有的幂函数形式并保持回归参数不变 ,通过增加位置参数反映现场试验的个性信息。其修正后的结果既反映混凝土回弹值和强度值之间的一般关系 ,又反映现场试验的实际情况。在混凝土回弹检测中采用该曲线 。The accuracy of the concrete strength obtained from on site testing is closely associated with the security of structure. Through fusing the common information from the general strength rebound curve and individual information from on site test, a relation curve between the concrete strength and rebound value corresponding to field condition is obtained. The curve retaining the original power function and regression parameter could reflect on site individualized information by adding location parameter. The revised result could reflect simultaneously the common relation between the concrete strength and rebound value, and the actual condition of on site test. By using this curve, both the precision and reliability of the testing result could be greatly improved.
