• ### Studying collapse potential of gypseous soil treated by

The leaching of gypsum from soil changes the physicalchemical and the mechanical properties of the soil with the development of large settlement (Mikheev et al., 1973). Several methods have been used to minimize the collapse potential of gypseous soil, such as replacing the gypseous soil or stabilizing it (grouting or soil improvement).
