Plaxis analysis for ultimate footing bearing capacity (disp_Control) on compacted sandy soil overlying loose sand.

Plaxis analysis for footing on compacted sandy soil (subexcavation and backfill to increase bearing capacity) overlying loose sand. 

Soil Collapse occurs way before real failure. All options (fine mesh, interfaces between different materials, various modules for materials) were investigated and yielded different outputs with various settlement at stop. 

Plaxis yieds not consistent results and difficlut to correctly define ultimate bearing capacity from analyese.
