運用非破壞性檢測技術以評估基樁之完整性及施工品質已是趨勢。平行震測法是非破壞檢測制式規定方法之一。然而,使用平行震測法之相關研究較少。本研究之目的是探討利用平行震測法檢測基樁長度的準確性。本研究利用現場植入之預製不同缺陷大小之PC樁為試驗樁,各別進行完整樁及缺陷樁之檢測。研究方法係利用量測基樁各深度與傳播初始速度之時間振幅圖再進行分析。結果顯示,量測樁長與實際樁長相符,預製之缺陷在本方法時域資料無法有效判讀。
Using nondestructive testing to evaluate the integrity and construction quality of newly-built piles become a routine regulation. Parallel seismic (PS) method is one of nondestructive testing methods. However, there are limited studies of parallel seismic method used for this purpose. The purpose of this study is to check the accuracy of the length evaluation of a pile by using the parallel seismic test method. In this study the precast piles are pre-constructed with different size of defects in the pile. The impulse hammer hits the pile head, the echo signals is used to determine the initial arrival time of each depth. The length of pile is evaluated from the initial arrival time. The results show that the length of pile obtained from using PS method is matched well with the actual length of pile. But the defect of piles is difficult to be detected by this method.
