Abstract

This paper presents a three-dimensional numerical model for the prediction of free field vibrations due to the vibratory and impact of pile driving. A new coupling methodology, finite element method (FEM) with scaled boundary finite element method (SBFEM), has been adopted to simulate the pile driving process into a layered ground. With this numerical model, the reflection energy can be absorbed on the near-/far-field interface without accuracy reduction, while simulation time and amount are reduced. The results indicate that the ground surface vibration during piling will not be affected whilethe receiver is located away from source over than five times of pile diameter with vibration frequency fixed at 20 Hz.
