Abstract: In this paper, a synthetic test method is presented based on the dynamic characteristic test criterion of pile. This method combines sine excitation with shock excitation. Using this method, the dynamic characteristics of test piles in thermal power plant are tested. The model analytical technique is used to identify the model parameters of single pile. The vertical dynamic stiffness of the pile can be computed by these model parameters.
Keywords: Pile, dynamic stiffness, synthetic test method, data processing.
