Abstract: The composite ground consisting of rigid columns has received more and more applications in recent years. With its advantages over other soil improvement methods, it receives especially wider applications in the warehouse, roadway and airport projects. This paper presents a case history of applying the rigid column technique in a soil improvement of thick cohesive soft soils for a logistic warehouse project. Several feasible soil improvement methods were compared and it was found the rigid column method was the most applicable one. The bearing capacity of the rigid column and the settlement of the composite ground were checked and the results were satisfactory.
