| 摘 要： | 以超声回弹综合法相关规程为依据，通过大量的试验数据分析，建立了适用于旧混凝土强度检测的超声回弹综合法的专用测强曲线。以实际工程为依托，对比分析了漳州十里桥相应的长龄期混凝土钻芯试验结果，验证了回归测强曲线的精度，结果表明超声回弹综合法的专用测强曲线误差较小、可信度较高。

| Abstract: | A special strength curve was established for old concrete strength detection by ultrasonic-rebound method, based on ultrasonic-rebound method related disciplines and a lot of experimental data analysis. The measurement pre- cision of regression curves was verified through analyzing old concrete core test of the Zhangzhou Shili Bridge in actual engineering. Results showed that the exclusive strength curve of ultrasonic-rebound synthesis bad low strength and high precision. |
