【摘要】 基于长龄期混凝土在龄期上不能满足现行的CECS 02:2005《超声回弹综合法检测混凝土强度技术规程》中普通测强曲线的要求,对所收集的100组龄期为20～25 a的碎石混凝土原结构超声-回弹-钻芯数据进行回归和误差分析;拟合出武汉地区长龄期碎石混凝土超声回弹综合法测强曲线,并结合实际工程检测验证曲线精度。更多还原

【Abstract】 Based on the situation of long-age concrete can’t satisfy the accuracy testing concrete strength by CECS 02:2005 of Technical Specification for Detecting Strength of Concrete by Ultrasonic-rebound Combined Method,regressions and errors analysis about the strength of real structure concrete with the combination of ultrasonic-rebound and core-drilling from 20 to 25 years among 100 pairs,the long-age rubble concrete ultrasonic-rebound-strength curve for Wuhan district is gained,at the same time,the accurate curve is showed according to the engineering test.更多还原
