Two-dimensional study of the inclusions of skirt sand and deep cement piles to improve the load‒displacement behavior of circular foundations on soft clay soil
TL;DR: In this paper , a two-dimensional finite element model was used to improve the bearing capacity and settlement of soft clay soil by employing skirt sand piles, and the results were compared with reinforced cement piles.

The strength and dilatancy of sands
TL;DR: In this paper, the strength and dilatancy of 17 sands in axisymmetric or plane strain at different densities and confining pressures are collated, and the critical state angle of shearing resistance of soil which is shearing at constant volume is determined experimentally within a margin of about 1°, being roughly 33° for quartz and 40° for feldspar.

Behavior of Stone Columns Based on Experimental and FEM Analysis
A. P. Ambily,S. R. Gandhi +1 more
Abstract: A detailed experimental study on behavior of single column and group of seven columns is carried out by varying parameters like spacing between the columns, shear strength of soft clay, and loading condition Laboratory tests are carried out on a column of 100 mm diameter surrounded by soft clay of different consistency The tests are carried out either with an entire equivalent area loaded to estimate the stiffness of improved ground or only a column loaded to estimate the limiting axial capacity During the group experi- ments, the actual stress on column and clay were measured by fixing pressure cells in the loading plate Finite-element analyses have also been performed using 15-noded triangular elements with the software package PLAXIS A drained analysis was carried out using Mohr-Coulomb's criterion for soft clay, stones, and sand The numerical results from the FEM are compared with the experimental results which showed good agreement between the results Columns arranged with spacings more than 3 times the diameter of the column does not give any significant improvement Based on the results, design charts are developed and a design procedure is suggested

The settlement performance of stone column foundations
TL;DR: In this article, the authors present results obtained from physical model tests on triaxial specimens 300 mm in diameter and 400 mm high and show that the settlement performance of a small column group is highly influenced by inter-column and footing.

Effect of soil improvement on ground subsidence due to liquefaction
TL;DR: In this paper, the authors conducted detailed site surveys at the liquefied sites and found a remarkable phenomenon. Some zones in two big artificial islands, Port Island and Rokko Island, in Kobe City, did not liquefy even though the zones surrounding the islands liquidated, and they found that the non-liquefied zones had been improved by several methods, including sand compaction piles, rod (vibro) compaction, sand drains and preloading.

Mode of Failure of a Group of Stone Columns in Soft Soil
TL;DR: In this paper, a numerical model was developed to simulate the case of a single stone column and a group of stone columns installed in soft clay, and the model established the level of interaction between individual columns and therefore determined the mode of failure of a given geometry, soil, and loading condition.
