中文摘要 | 本研究之目的乃量求敲擊回音法作混凝土表面量測時,量測P波波速和檢測裂縫深度之適當探頭位置配置,作為日後應用此法作檢測時之參考。由試驗之結果得知,量測P波波速之兩探頭距離為10cm時,敲擊點到第一接收探頭之適點距離為3cm~14cm;為20cm時,敲擊點到第一接收探頭之適當距離為5cm~28cm;為30cm時,敲擊點到第一接收探頭之適當距離為3cm~17cm。量測裂線深度時,當敲擊點到裂縫距離為5cm ~6cm,第二接收探頭到裂縫距離為5cm~11cm,第一接收探頭到膏擊點距離為5cm~7cm的探頭配置,可以適用於檢測表面開裂裂縫之深度。 |
英文摘要 | This paper is to find out the suitable distance arrangement of transducers for measuring P-wave velocity and the depth of surface cracks in concrete when using the impact-eco method to perform a surface measurement. The results show that, for measuring P-wave speed, the suitable distance between impact point and the first transducer is 3~14 cm when the distance between two transducer is 10 cm, is 5~28cm when the distance is 20 cm, and is 3~17 when the distance is 30 cm. For measuring the depth of crack, the suitable distance between impact point and the first transducer is 5~7 cm. The suitable between crack and the second transducer is 5~6 cm. |
