Numerical and Experimental Studies of Wave Propagation Induced by Pile Driving
Abstract: This paper presents
results of numerical and experimental studies to predict the peak particle
velocity (ppv) induced by a pile
driving. By utilizing
a professional finite
element software, Plaxis
2D Dynamic, this
study analyzed ppv due to pile driving in clays for various
soil stiffness and various embedded pile lengths. For verification, a full
scale field test of pile driving was performed in East Kalimantan with
installed instrumentations of accelerations. Results of both instrumentation
and numerical analysis show that ppv depends on distance and soil rigidity. The
closer the object to pile tip, the larger the ppv that will be produced. The
more rigid the soils at the pile tip, the larger the ppv, too. The
results also show
that both field
test and numerical
analysis results are
comparable. Finally, this
paper proposes a chart
to predict the ppv
of soils due
to pile driving in
clays. The output of the proposed
method is the predicted ppv for various distances from
pile driving location.
