TLDR
In this article, the effects of pile spacing, number of piles, and configuration on displacement and bending response of pile groups in clay under dynamic lateral loading were investigated, and strong group interaction leads to significant differences in bending profiles of different row piles of the groups.Abstract:
The effects of pile spacing, number of piles, and configuration on displacement and bending response of pile groups in clay under dynamic lateral loading were investigated. The displacement response of pile group in clay is strongly nonlinear. Pile-soil-pile interaction is predominant for the groups with closer spacing and with greater number of piles. Group interaction causes reduction in the group stiffness and increase in damping of the pile group. Strong group interaction leads to significant differences in bending profiles of different row piles of the groups. Dynamic lateral loading increases the maximum bending moment and active pile length.read more

Comparison on the Horizontal Behaviors of Lattice-Shaped Diaphragm Wall and Pile Group under Static and Seismic Loads
TL;DR: In this paper, a numerical study of the comparison of the static and seismic responses of LSDW and pile group under similar material quantity in soft soil was conducted. And it was found that the horizontal bearing capacity of LSDw is considerably larger than that of pile group, while pile group clearly shows a local bending deformation pattern during the static loading process.
