摘要: 本論文主要目的乃探討以頻率及遠距離反射波法(方法一) 、可感測敲擊器配合單一垂直位移接收器(方法二)、可感測敲擊器配合單一水平位移接收器(方法三)、ASTM C1383雙垂直位移接收器(方法四)、ASTM C1383雙水平位移接收器(方法五)等五種方法推算混凝土厚度,利用此五種方法量測現地已知厚度之混凝土版,並比較分析量測結果的差異性。 為了有效率地檢測現地混凝土版狀結構厚度,本研究採用(C1383-Modified,FF Plate Thickness Test Method) (方法一)及(SEC_NDT_02.2_C1383 Plate Thickness Test Method) (方法二〜方法五)兩套程式,兩程式外觀皆為圖形化之使用者介面,頻率_遠距離反射波法(C1383-Modified,FF Plate Thickness Test Method)(方法一)藉由量測版底反射P波及混凝土版厚頻率來推求混凝土版厚度及內部P波波速;而ASTM C1383(SEC_NDT_02.2_C1383 Plate Thickness Test Method)(方法二〜方法五)則是藉由量測表面P波及混凝土版厚頻率來推求混凝土版厚度。試驗結果顯示, 現地混凝土版厚度量測之準確性取決於版厚頻率及混凝土波速兩項因素皆可得到正確量測值,多種方法之量測比較有助於確認現場量測之結果。
The purpose of this thesis is to investigate the application of the stress wave techniques to concrete plate thickness measurement. Five measurement methods are used. The first one makes use of the frequency response combined with the far distance reflection wave method (Method one). The second one uses an impact device able to record the start time of impact and a receiver sensing the vertical surface displacement (Method two). The third method adopts an impact device able to record the start time of impact and a receiver sensing the horizontal surface displacement (Method three). The forth method uses two vertical receivers according to ASTM C 1383 (Method four). The final one employs two horizontal receivers and follows the ASTM C 1383 test procedure (Method five). A comparison of the in-place measurement results among these five methods is made and the difference between the measurement values and the known thicknesses is discussed. For the efficiency on measurement of concrete thickness, this thesis uses two sets of programs which are presented by graphic interface, called C1383-Modified, FF Plate Thickness Test Method for Method one and SEC_NDT_02.2_C1383 Plate Thickness Test Method for Method two 〜 five. The program C1383-Modified, FF Plate Thickness Test Method (Method one) adopts the travel time of the P-wave propagating from the impact point through the bottom reflection to the receiver at a point far away from impact and the thickness frequency of the plate and after measurement the velocity of internal P-wave and the plate thickness can be obtained simultaneously. The program SEC_NDT_02.2_C1383 Plate Thickness Test Method (Method two 〜 Method five) measures the surface P-wave velocity and the thickness frequency of the plate to estimate the thickness of concrete plates. Experimental results show that the accuracy of the thickness measurement depends on the accuracy of measurements on the thickness frequency and the wave velocity. Use of multiple measurement methods is of great help in making the measurement results reliable.
