The practice of construction and operation of irrigation facilities on loess nodded soils shows that properly designed facilities, which are erected with high quality, can work for a long time without violating their operational suitability. At the same time, the specificity of the engineering and geological conditions of certain regions of the Republic of Uzbekistan, i.e. for strongly and inhomogeneous subsidence soils, it requires correcting some provisions of regulatory documents, to take into account the peculiarities of the stress-strain state of the “structure -subsidence base” system, which depends both on the structure of the hydraulic structure and the physical and mechanical properties of the soil changing during moistening. The specifics of the work of hydraulic structures consists that in the overwhelming majority of cases, their soil bases are moistened to the level of maximum water saturation. However, in the first time after the commissioning of the hydraulic structure, the soil mass is moistened unevenly, which affects the nature of the interaction between the foundation and the structure. The article presents the results of studying the patterns of stress variation in subsiding ground foundations in experimental studies of the stress-strain state of the loess bases of tubular crossings, which are widely distributed in irrigation systems of the south of the Republic of Uzbekistan.
