“Analysis of Stone Columns in Soft Soils under Vertical Loading Considering the Construction Effects on the Enfolding Soils"

Abstract

Ground improvement using stone columns is one of the most common ground improvement techniques used in soft soils. The design of soil-column-footing systems depends on major simplifications. One of these simplifications is to ignore the effect of stone column installation on enfolding soft soils. Many studies have been performed to examine the real behavior of stone column foundations; however, few studies have investigated the effect of the stone column installation technique on the enfolding soft soil and how to implement this effect on the design procedure, with recommendations for designers.
