What is it about?
This paper focuses on evaluating the load-settlement response of circular footings on unsaturated soil layers improved with stone columns using 1-gravity (1g) physical modeling experiments.

Why is it important?
Results indicate that changes in the initial degree of saturation of the soil layer can have a major effect on the bearing capacity of the soil layer, the soil failure mode during loading of a surface footing, and the deformation interaction responses of the soil layer and the embedded stone column.
Perspectives
This paper is the first paper in the field that tackle the topic of stone columns in unsaturated soils. Previous studies have ignored the unsaturated soil condition and have mainly used the saturated soil parameters in designing stone columns which leads to uneconomical design especially in arid and semiarid regions where the soil is mostly at unsaturated state. The authors believe that this paper will lead to a great contribution to the geotechnical engineering designs and will be the primary reference for future similar works.
