TL;DR: In this article, a series of 1g model tests were conducted to investigate the accumulated vertical pullout displacement and unloading stiffness of bucket foundations embedded in dry and saturated sands, and empirical equations were proposed for the preliminary design of single or tripod bucket foundations.

TL;DR: In this paper, the bearing capacities of tripod bucket foundations were analyzed in medium and dense sand by performing a series of 3D finite element analyses, and it was shown that the horizontal bearing capacities reached the maximum values at a spacing ratio of S/D =15 to 35 for the foundation with an embedment ratio of L / D =05 to 1 (where S is the bucket spacing, D is bucket diameter, and L is the skirt length of the tripod bucket).

TL;DR: In this article, the effect of slope on the dynamic behavior of pile-supported structures by performing a series of centrifuge tests was evaluated by applying the piecewise cubic spline method to fit the measured bending moment curves along piles.

TL;DR: In this paper, a 3D numerical model of a single pile in sandy soil was built to analyse the interface strength parameter, which was defined as the ratio of the lateral force mobilised on the interface to the confining stress multiplied by the pile perimeter.

TL;DR: In this paper , a series of numerical simulations of a single pile in cohesionless soil subjected to lateral loading were performed by considering various slope configurations, soil densities, and loading directions.
