Title of the articleInvestigation of deformations of clay soils under regime of prolonged triaxial compression taking into account initial defects
Abstract. Construction of deep pits leads to changes in the stress-strain state of the soil mass within the radius of the zone of influence. This is caused by base unloading during excavation, horizontal displacement of excavation walls, technological factors. When falling within the zone of existing development, there is a need to assess and geotechnically predict the behavior of the foundations of existing buildings and structures. Existing and newly emerged Известия КГАСУ, 2021, № 4 (58) Основания и фундаменты, подземные сооружения 13 defects and damages of soils must be taken into account. The aim of the study is to determine the dependences of the main deformation characteristics of clay soil with existing defects on the basis of laboratory studies, for this purpose it is necessary to: conduct an experimental study in triaxial compression of clay samples with cracks and without cracks; establish the peculiarities of crack development in the clay sample structure; to establish the peculiarities of deformation development of cracked clay soil under triaxial compression.
Keywords.clay soil, deformations, microcracks, macrocracks, bearing capacity, rheology of soils.
