K. Miura et al., DYNAMIC BEHAVIOR OF PILE FOUNDATIONS IN HOMOGENEOUS AND NONHOMOGENEOUS MEDIA, Earthquake engineering & structural dynamics, 23(2), 1994, pp. 183-192
A three-dimensional formulation based on Green's functions of cylindri
cal loads in layered semi-infinite media is employed to investigate th
e dynamic behaviour of piles in homogeneous and non-homogeneous half s
paces. The pile-soil-pile interaction taking place in pile groups is i
ncorporated in the model. The results presented in this paper include
the dynamic stiffnesses and dampings of single piles as well as those
of representative 2 x 2 and 4 x 4 square pile groups in the soil media
considered in this study. In addition, the distribution of forces app
lied on the pile cap among the individual piles in a group is investig
ated.
