| Title of the article | Influence of the hardening process on the strength of clay soil under regime triaxial loading |
| Abstract. | Problem statement. Under the conditions of the regime long-term loading in the ground at the same time arise changes in the deformation volume and shape, which influence to each other, leads to strain rate stabilization and even deformation attenuation or progressive soil creep. Herewith, in the calculation model, the effect of these processes on the soil mass deformation and strength is reflected insufficiently. Results. The article presents theoretical and experimental study results of the hardening process effect to the clay strength under the regime triaxial loading. It is found that in the process of the regime triaxial loading occurs simultaneous clay soil hardening and softening, wherein the deformation process can lead to the destruction as a result of deformation progressive or stabilization. The main criterion for the destruction of clay soil is a critical damage degree value by microcracks in the equilibrium zone limit. Conclusions. At the regime triaxial loading of clay soil samples of disturbed structure by restoring the structural links, soil strength indicators are increased from 5 % to 15 %. |
