Simulating the effect of vibratory pile driving on far field of a driven pile

摘要

The rapid increase in construction activities in past few decades has made the land a scarce resource.rnThus, many new construction projects in urban environment are carried out in the vicinity of existingrnbuildings. The construction induced vibrations can inflict significant forces on the substructures ofrnadjacent buildings. This paper investigates the effect of vibratory pile driving on far field of the drivenrnpile. First, the effectiveness of wave transmitting boundaries used to truncate the finite element meshrnin the dynamic finite element modelling is studied. Pile installation is simulated from the groundrnsurface and the finite element model is verified using the field data available in the literature. Then, thernsame model is used for a dynamic analysis with wave transmitting boundaries to study the groundrnvibration propagation around a driven pile.
