摘要
欲獲得正確之基樁承載力,有賴正確之載重試驗方法。本文係針對靜載重試驗方法、監測系統及相關事項逐一說明,祈能提供相關業者對試樁規範之內容能有多一層參考。此外並介紹打樁動力分析(PDA)及動力載重試驗方法(DLT),及利用國內試樁案例說明動力分析可以改進基樁施工效率及驗證基樁施打後之品質。最後介紹國外最新之靜動荷重試驗方法,其原理及試樁實際案例。以期借此三種方法靈活運用使國內之基樁品質控制能達到較經濟有效之目標。
英文摘要
The correctness of pile capacity comes from accurate and reliable load testing methods. This paper addresses the method of pile load test by means of dead weight, The associated instrumentation for data acquisition, and highlights some practical problems. Secondly, the concepts of Pile Driving Analysis (PDA) and Dynamic Load Test (DLT) are presented in details. Local case records on pile load tests are used to demonstrate that PDA and DLT can be applied to improve the driving efficiency and to check the quality of driven piles. Finally, the latest pile load test by statnamic method is introduced. Some actual pile test results are cited for reference. With the application of these testing methods, better quality of pile load test may be achieved at lower cost.The correctness of pile capacity comes from accurate and reliable load testing methods.
