The aspects of determining the moduli of unloading and reloading of dispersed soils were considered. Sample tests involving triaxial compression devices showed that these parameters depend on the stress-strain state. The ratios between the primary loading and reloading moduli accepted in design practice were significantly underestimated, which led to errors in determining the settlement of structures. In accordance with the results of the study, a methodology for determining the moduli of unloading and reloading was proposed.
