高精度打声法在混凝土内部缺陷检测中的应用

Application of High-precision Resonance Acoustic Method in Detection of Internal Defects of Concrete

打声法作为一种简便易行的无损检测方法,在建筑、土木工程的质量检测(如混凝土浇筑密实度等)中得到了比较广泛的应用。文章介绍了打声法的特点,提出了一种高精度的打声测试方法,并利用混凝土试块进行了验证。

As a simple non-destructive testing method, resonance acoustic is widely used in construction for the civil engineering quality control such as the density of concrete pouring and so on. After introducing the features of resonance acoustic, a high-precision acoustic test method is proposed in the paper. By using the concrete test blocks, the method is verified.
