摘要


以表面反射法為基礎之基樁非破壞檢測技術已被廣泛運用於新建場鑄基樁之完整性檢測試驗上,而傳統的非破壞檢測系統有:體積龐大、按鍵繁多、介面呆版、指令複雜等問題。 本論文利用現有的衝擊鎚及加速度規,以LabVIEW 8.6軟體為開發環境,使用類比數位轉換卡進行波型訊號之擷取及轉換成數位數據,研發出一套表面反設法原理為基礎的基樁完整性。本論文整合前人所開發之音波回音法與脈波反應法非破壞檢測軟、硬體,並增加了依時指數放大功能。對於埋設在土壤中之基樁而使得反射訊號隨深度而衰減,因為依時指數放大之功能使得缺陷式樁底之訊號更容易判定。為驗證本論文所開發之軟硬體之可行性,本研究亦針對本系非破壞檢測試驗場之三根模型基樁進行檢測,結果顯示此一系統可正確判斷出基樁之缺陷類型,故可推廣至實際應用上。

並列摘要


The surface reflection non-destructive testing technique has been widely used for the integrity testing of the cast-in-place piles. There are several defects in the traditional non-destructive testing system, such as huge size, redundant buttons and rigid user interface, etc. In this study, a non-destructive testing system based on surface reflection technique was developed. The hardware utilizes existing impact hammer and accelerates. An analog to digital card was used to capture the test signal. A software which integrates the sonic echo and impulse response method with exponential amplification function was developed using LabVIEW. To verify the feasibility of the hardware and software developed in this study, three model piles with various defects were tested. The results show that system can identify the defects within these three model piles.Therefore, it is feasible to implement this system into practical application.
