| Evidence from one of the objects in Ukraine with a recessed substructure
there were considered aspects of supporting subsoil softening over time. Deformations of differential movement of the foundation pit bottom cause to uneven slumps due to more intensive subsoil softening under the central part of the pit, compared to its edges and corners. Completed laboratory studies of the soil yielded a picture of the soil physical change with stratification depth, and as a result the corresponding characteristic curves were obtained. It was proposed to call the described process and its accompanying phenomena as soil reconsolidation, and the term "reconsolidation factor" was introduced. The authors have proposed the typology of soils, on the base of which the occurrence of the soil softening effect may be predicted. |
