Evaluation of Stability of Embankment Constructed on Soft Consolidating Soil with Lime–CFG Composite Column System

Abstract Effectiveness of providing lime and CFG composite column system on the safety factor embankment constructed consolidating soil is studied at different time intervals during consolidation foundation soil. The effectiveness compared with only or columns. In addition, settlement process also investigated. Embankment, columns are modeled using finite element method. Numbers trial surfaces center radius generated each interval critical surface selected to calculate effective stresses obtained by analysis. From study, it concluded that provision columns, either individually in combination, reduces improves factor. However, most type their arrangement reduce may not be enhance hence, arrangements has considerable influence purpose for which provided.
