Stone column is one of the most effective techniques used in soil enhancement. Inserting stone
columns under strip footing in the active zone of a retaining wall embedded in soft soils enhances the allover
behavior of the retaining wall. Stone columns improve the bearing capacity under the footing, decreases the
settlement of the footing, and decreases the lateral movement of the retaining wall. Increasing area replacement
ratio of stone columns improves the bearing capacity under the footing, reduces settlement, and decrease the
lateral movement of retaining wall.In this resaerch an experimental study was carried out on changing the area of
replacement ratio of stone columns inserted in very soft clay in the active zone of embedded retaining wall with
strip footing load at the top of backfill.Increasing stone columns area replacement ratio improves the bearing
capacity under the footing, reduces settlement, and decrease the lateral movement of retaining wall. |
