Abstract
One of the techniques to support embankments is to use a deep mixing method with the addition of structures in many countries. The design has some measurable criteria such as analyses of settlement and stability, even though deep mixed materials are changeable. The primary emphasis of this research is on stability of embankments supported on columns installed by the deep mixing method. Several numerical analyses about the wet method and the dry method have been done in this paper; the dry method includes lower water content of improved soil, lower binder quantity and ordinarily much more strength, while in the wet method it is easier to produce homogeneous columns. Column supported embankments are constructed over soft ground to speed up construction, enhance stability of the embankment, minimize total and differential settlements, and protect adjacent resources. The columns should be durable and stronger than the existing site soil, and if correctly designed, they can impede immoderate movement of the embankment.
