In this article, the authors analyzed the possible causes of deformation of buildings and structures that are built on subsiding loess soils. The research is based on a systematic analysis of the expert practice of identifying the reasons for the deterioration of the technical condition of objects built and operated on such soils. The mechanisms of the development of subsidence deformations of loess soils are considered and the reasons for the change in their hydrogeological regime are analyzed. The main factors and sources are systematized, which with a high probability can lead to changes in the hydrogeological regimes of soils during the construction and operation of buildings and structures operated on subsiding loess soils. Particular attention is paid to the study of the reasons for changes in the hydrogeological regime of soils, which lead to a discrepancy between the calculated characteristics of the soil foundations that were used in the construction of the facility, their actual value. It is shown that this discrepancy is one of the main hidden causes of flooding of buildings and structures, which can lead to uneven subsidence. The relationship between the appearance or development of damage to the building structure and the probable reasons for the deterioration of its technical condition is systematized.
