Some laws of deformation of clayey soils
Conclusions 1. In the behavior of clayey soils under natural occurrence conditions, two basic stages can be singled out: the elastic stage, limited by the structural strength surface, and the elastoplastic. In the elastic region, structural collapse may occur. The elastoplastic region should be divided into zones of dispersed and localized shear. 2. The structural strength surface can be approximated by two surfaces characterized it for shear and compression. 3. The reliability in the determination of the structural strength for well-taken samples is ensured by reducing their conservation period, by recommending them before testing, and by measuring the deformations in the middle portion of the samples. 4. Plastic flow for dispersed shear can be described on the basis of the critical state concept. An important characteristic of soils is the stress surface for which there is shear localization. 5. The dilatancy rate in the limit state nonuniquely depends on the strength parameters.
