Factors Influencing the Behaviour of Flexible Pile Groups Under Lateral Loading in Soft Clay
TLDR
In this article, the lateral load deflection and bending behavior of flexible pile groups embedded in soft clay was investigated and the effects of embedding length of pile, magnitude of applied lateral load, size of group, row and column wise position of pile in the group, cyclic loading and presence of vertical loading on lateral response of pile group were evaluated.Abstract:
Experimental investigation is carried out to study the lateral load–deflection and bending behaviour of model flexible pile groups embedded in soft clay. The effects of embedment length of pile, magnitude of applied lateral load, size of group, row and column wise position of piles in the group, cyclic loading and presence of vertical loading on lateral response of pile group are evaluated. Results from the tests reveal that flexible piles subjected to lateral load greater than about 60 % of ultimate lateral load cannot be considered as flexible. Maximum bending moment of front row pile of 3 × 3 group is about 16 % higher than that of middle row pile. Within the same row piles, corner pile has about 10 % higher bending moment than that of middle pile. Maximum bending moment in pile subjected to 15 cycles of loading is about 80 % higher than that for static loading. The lateral capacity of the 3 × 3 pile group with 60 % of ultimate vertical load is about 18 % less than that of the pile group with no vertical load.read more

TL;DR: In this paper, the authors used the horizontal asymptote of the hyperbolic model to estimate the ultimate bearing capacity of a foundation, which yields a value very close to other conventional bearing capacity methods.

TL;DR: In this paper, the authors present a consistent theoretical approach to the prediction of pile deformation and load capacity, and present parametric solutions for a wide range of cases, demonstrating how such solutions can be used for design purposes, and review the applicability of these approaches to practical problems.

The response of flexible piles to lateral loading
TL;DR: In this article, a parametric study was conducted using the finite element method and treating the soil as an elastic continuum with a linearly varying soil modulus, and the results of a simple algebraic expression for the active length of the pile; the ground level deformations; and the maximum bending moment down the pile were presented.

Lateral Load Behavior of Full-Scale Pile Group in Clay
TL;DR: In this article, a static lateral load test was performed on a full-scale pile group to determine the resulting pile-soil-pile interaction effects, and good agreement between the measured and computed pile group responses was obtained using the p-multiplier approach.
Cyclic Lateral Loading of Large-Scale Pile Group
TL;DR: In this paper, a large-scale group of nine steelpipe piles in a closely-spaced arrangement was subjected to two-way, cyclic, lateral loading with water above the ground surface.
