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. This is caused by the unloading of the base during excavation, horizontal movement of the walls of the pit, technological factors. When entering the zone of existing buildings, there is a need for an assessment and geotechnical forecast of the behaviour of the soils of the foundations of existing buildings and structures. At the same time, it is necessary to take into account existing and newly arisen defects and damage to soils. The purpose of the study is to determine, based on laboratory studies, the dependences of the main deformation characteristics of clay soil with existing defects, for this it is necessary: to conduct an experimental study with triaxial compression of clay samples with cracks and without cracks; to establish the features of the development of cracks in the structure of the clay sample; to establish the features of the development of deformations of clay soil with cracks with triaxial compression. Based on the results of the study, new data on the affect of defects in soil samples were obtained. Based on the research results, the dependences of the main deformation characteristics of clay soil are constructed. The significance of the results obtained for the construction industry lies in the fact that they make it possible to more accurately assess the settlement of foundations when constructing deep pits near existing buildings.
