【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。更多还原

【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 precision 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 had low strength and high precision.更多还原
