Engineering-geological conditions and interactions of technogenic processes with the environment

The article discusses very pressing problems associated with the engineering and geo-ecological conditions of the city of Zarafshan and adjacent territories, in connection with the expansion of industrial and civil construction. The purpose of the research is to study the engineering and geo-ecological conditions of the distribution of bentonite clays, which are the basis of structures and the intensive development of natural and manmade processes. Modeling shear deformations of foundations on swelling clays is one of the most complex material systems. Swelling clays of the Eocene have pronounced features of deformation behavior, which must be taken into account when assessing deformations and justifying construction projects. Based on this, a danger affecting the stability of the structure is clay shrinkage. Based on the engineering and geo-ecological studies carried out on the territory of the city of Zarafshan, the values of the total deformation of swelling Eocene clays under different loads from the structure for a single-layer model were established. With a constant load from the structure and a variable load of swelling-shrinkage, a system of annually repeated impacts is formed, mainly precipitation and economic activity, which creates a danger for the stability of buildings and structures and the surrounding geo-ecological environment.
