Title: Clay soil deformations under regime long-term triaxial compression taking into account initial defects
Abstract: The arrangement of deep pits leads to a change in the stress-strain state of the soil mass within the radius of the zone of influence. When entering the zone of existing buildings, there is a need for an assessment and geotechnical forecast of the behavior of the soils under foundations of existing buildings and structures. At the same time, it is necessary to take into account existing and new defects and cracks in soils. For determine the main dependences of clay samples deformation characteristics with existing defects experimental studies with triaxial compression of samples with cracks and without cracks were carry out. Based on the results of the study, new data were obtained on the effect of defects in soil samples on the deformation of clay soil. Based on the research results, the dependences of the main deformation characteristics of clay soil are constructed.
