應力波方法決定鋼筋混凝土基樁之承載力
Determination of Bearing Capacity of Reinforced Concrete Pile by Stress Wave Method
摘要
本文旨在探討應力波方法預測鋼筋泥凝土基樁軸向承載力之可行性。於實驗部份，將六根不同條件之模型樁分別打設於乾砂中，俟其穩定後對樁頭施加衝擊荷重，並同時記錄基樁之受力、速度及位移對應時間關係。分析時採用CASE方法及TNO方法預測靜態軸向承載力並與靜載重試驗結果進行比較。分析結果顯示動態試驗所得與應力波理論之分析模式相吻合，而較靜載重試驗結果高；因此，於配合適當安全係數條件下，將應力波方法運用於現地基樁工程上應屬可行。

The principal purpose of this paper is to study the serviceability for predicting the axial bearing capacity of reinforced concrete pile by stress wave method. In order to verify that the dynamic method could be replaced of static loading test, six model piles made of reinforced concrete are driven into dry sand for doing dynamic experiment. Both the CASE and TNO methods are used to analyze the experimental results. The analytic results obtained from the CASE method are very approached to the TNO method does. However, these results analyzed from the CASE and TNO method are higher than the static loading test case. If one uses the dynamic measurement to determine the axial bearing capacity of pile in practical engineering, then engineering disaster will be reduced.
