摘要
弹性波法是近年来快速发展的混凝土结构无损检测方法之一。根据混凝土剥离区域刚性显著降低、卓越周期变长、弹性波的逸散推迟等特征,可检测不同缺陷适用的特征参数,进而对混凝土内部剥离缺陷进行检测和评估。在某实际工程应用中,根据剥离云图,结合频谱MEM分析,推断出缺陷位置及尺寸。
The method of elastic wave is one of the important nondestructive testing techniques for concrete,which is developed rapidly in recent years. Including the reducing rigid at the debonding defects area, elongating predominant period, dissipation delay of elastic wave, the different characteristic parameters which are detected in the concrete with defects are obtained to evaluate the concrete debonding defects. Combining with the actual project, the defects location and dimension are ensured based on the debonding nephogram and MEM analysis.
