摘      要：Deep foundations are currently used in engineering practice to solve problems caused by weak geotechnical characteristics of the *** pile driving is an interesting and viable solution from economic and technical points of ***,it is necessary to ensure that the environmental drawbacks,namely ground-borne vibration,are adequately *** this purpose,the authors propose an axisymmetric finite element method-perfectly matched layer(FEM-PML)approach,where the nonlinear behavior of the soil is addressed through an equivalent linear *** the complexity of the problem,an experimental test site was developed and fully *** experimental work comprised in-situ and laboratory soil characterization,as well as the measurement of vibrations induced during pile *** comparison between experimental and numerical results demonstrated a very good agreement,from which it can be concluded that the proposed numerical approach is suitable for the prediction of vibrations induced by impact pile *** experimental database is available as supplemental data and may be used by other researchers in the validation of their prediction models.
