Abstract: This paper summarizes the characteristics of chromite ore processing residue (COPR) in terms of their chemical compositions, phases, and recycling potential of iron and chromium through preliminary magnetic separation. ...

Abstract: The axial loading test on a geogrid-encased stone column has been simulated using 3D numerical model in the proposed study. The stone column was modeled using the discrete element method (DEM), and the geogrid was modeled ...

Abstract: The discrete element method–finite difference method (DEM--FDM) numerical simulation was conducted to investigate the failure process and the bearing mechanism of the single stone column in soft soil beneath rigid loading. ...

Abstract: Compared with isolated stone columns, a group of stone columns exhibits a much more complicated failure mechanism because of the complicated interactions between the respective columns and the surrounding soil under various ...
