| 利用非破壞檢測技術來評估新建單樁之完整性以及營造品質已是被許多國家採用的成熟技術。然而，欲將此類技術應用於現有橋樑基礎下之基樁則乃困難重重。主要原因在於檢測的複雜度因各種不同的結構元件的參與而大幅提高，例如重要的影響因素包含樁帽、群樁效應與礅柱等上部結構效應等。而基樁非破壞檢測方法中之「音波回音法」、「脈衝反應法」、「超震測法」與「平行震測法」在現地檢測上，具便利、經濟且又快速等優點，因此有待所有研究成果成熟後，此方法將可做第一線之非破壞檢測法。 本論文之目的在探討目前常用之應力波非破壞檢測（Nondestructive test NDT）技術對不同缺陷之檢測能力，利用已埋入土中之自行灌鑄之模型基樁，在其內部預先佈置大小、形狀不同之缺陷，並使用大小不同之敲擊鎚，及改變鎚頭之材質，比較音波回音法（Sonic Echo, SE）、脈衝反應法（Impulse Response , IR）、超震測法（Ultra Seismic , US）及平行震測法（Parallel Seismic , PS）等各種檢測技術對這些預設缺陷之檢測能力，期能找出最佳之基樁缺陷非破壞檢測方法。 |

| Using non-destructive testing （NDT） methods to evaluate the integrity and quality of newly-built piles is a mature technique and is adopted as a standard procedure by many countries. However, many difficulties have been encountered in applying these kind of techniques into evaluating the integrity of existing piles. The dominant factors include the effects of pile caps, pile group and superstructures. However, the NDT techniques such as the Sonic Echo, Impulse Response, Ultra Seismic and the Parallel Seismic methods have the advantages of being convenient, economical, and efficient. They can be used as the front line testing means once the related researches are matured. The main objective of this research is to investigate the feasibility of applying non-destructive testing techniques in evaluating the integrity of piles. Model piles with artificial detects were constructed and tested with impact hammer of various sizes and different tip materials. The ability of NDT technigues such as Sonic Echo, Impulse Response, Ultra Seismic, and Parallel Seismic methods in detecting these defects were compared in this thesis. |
