... Dynamic pile testing allows examination of the capacity and integrity of deep foundations. The analysis of stress wave propagation in piles is based on the application of the one-dimensional wave equation (1D WE) for either matching measured to calculated signals (e.g., CAPWAP) or to analyze...

... a theoretical closed-form solution for a simple mass spring pile model, or calculated using the wave equation method. To increase the accuracy of the predictions, a learning loop approach is required for all of these approaches. Apart from predicting peak loads and load durations, the pile stresses, validity...

... piles. Piles were driven through medium dense to dense sand and stiff clay layers into the Kings Park Formation. A reinforced concrete infill was then constructed after the pile was driven to the design depth. During the tender phase, extensive wave equation driveability analyses were performed...

... was predicted by three static and two dynamic techniques. After testing, the predicted and measured capacities were compared. The wave equation and the Dutch cone penetration soundings resulted in the most consistent predictions. bearing capacity cyclic loads failure forecasting piles pile driving...

... potential, with N proportional to the factor of safety against liquefaction. The SPT can also provide the basis for the field-model determination of the J s , and J p damping coefficients in the wave equation analysis of pile-driving problems. An example indicates it may also correlate locally...
