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

Shape of ground surface settlement profiles caused by excavation

TL;DR: There are two general types of settlement profiles induced by excavation, the spandrel type and the concave type based on a regression analysis of the field observations of settlement curves with.

Horizontal Response of Piles in Layered Soils
George Gazetas,Ricardo Dobry +1 more
TL;DR: In this article, an inexpensive and realistic procedure is developed for estimating the lateral dynamic stiffness and damping of flexible piles embedded in arbitrarily layered soil deposits, where material and radiation damping due to waves emanating at different depths from the pile-soil interface are rationally taken into account; the overall equivalent damping at the top of the pile is then obtained as a function of frequency by means of a suitable energy relationship.

Bearing Capacity of Shallow Foundations
Wai-Fah Chen,William O. McCarron +1 more
TL;DR: In most, but not all cases, the serviceability or settlement criteria and the strength criteria may be treated as unrelated design tasks as discussed by the authors, which may be a short-term problem such as an embankment construction on an undrained clay foundation or a long-term problems in which the maximum foundation load may appear at some unknown time.
