In the test, an impact is applied on the surface of the concrete structure, and the response of the concrete due to the impact is measured and recorded
在彈性波試驗中，利用鋼珠或鐵槌敲擊混凝土表面，以產生應力波源，並以感測器測量混凝土表面反應。Thirdly, through assaying the error generated during measuring data, the result manifests : 1 ) the location installed of the transducer and the point thumped affects the experiment result to some extent. if surface - opening cracks is deeper, the location of the transducers installed and the point thumped should be further away from the location of surface - opening cracks. 2 ) when the depth of surface - opening cracks is near to 50mm, it is very difficult to measure the depth of surface - opening cracks because the depth of r _ wave conveying in concrete plates from the different small ball bringing forth exceeds 50mm. 3 ) it is clear from the experiment result, the influence is n ' t big for the diameters of small balls to measure the data while the time interval between two transducers touched firstly has very big influence on the result
其次，對測量數據進行了誤差分析，結果表明： （ 1 ）傳感器及敲擊點的位置對實驗結果有一定的影響，當開口裂紋的深度較深時，傳感器和敲擊點的位置應該離裂紋較遠； （ 2 ）當開口裂紋深度接近50毫米時，由於實驗中所使用的小球產生的r波傳播深度均超過50毫米，故很難測量出其開口裂紋的深度； （ 3 ）實驗發現，小鋼球直徑的大小對裂紋深度的測量結果影響並不是很大，但是，波的開始上升和下降點的測量精度（即兩信號的時間延遲） ，對測量的結果有很大的影響。
