锤击瞬态反应技术在混凝土结构检测中的应用

Application of Impulse Response Technique in Conditional Evaluation of Concrete Structure

通过实际工程应用介绍一种混凝土无损检测技术———锤击瞬态反应技术的原理、分析方法以及应 用。该项技术可用于非桩混凝土结构的无损检测,特别是对大面积结构构件进行快速内部探伤。实践证明该 检测方法操作简单,数据容易获取,检测速度快。

The principle and analysis method of a non-destructive testing technique-the Impulse Response(IR)test are desccribed,with emphasis on its application through case studies.Simple operation and rapid acquisition of test result are some of its advantages.In the past decade in the USA and Europe,this technique has been more widely used as a non-destructive testing tool to evaluate concrete upper structures,especially concrete elements with large surfaces.
