Settlement behavior of embankment on geosynthetic-encased stone columnn installed soft ground - A numerical investigation

摘要

This paper presents the results of a numerical investigation into the settlement behavior of embankment constructed on geosynthetic-encased stone column installed in soft ground. A three-dimensional finite element model was employed to carry out a parametric study on a number of governing factors such as the thickness and consistency of soft ground, the geosynthetic encasement length and stiffness, the embankment fill height, and the area replacement ratio. It is shown among other things that un
