    Abstract. When analyzing numerous deformations of residential buildings located on large thicknesses of sandy soils, it was found that the cause of accidents was the manifestation of liquefaction processes in the area of the sandy massif. Such phenomena were observed repeatedly during the construction of small industrial and civil structures, under the sole of which fine-grained, often with a high content of clay particles, sands were deposited. The article discusses the causes of the manifestation of the "liquefaction" processes of soils; the types of sands of various genesis and the features of particle interaction, taking into account micro-shells, are considered. In addition, useful data on the transition coefficient for determining the modulus of general deformation of sandy soils of natural composition based on the results of laboratory and field experimental data are presented. Data on the results of determination of strength characteristics on triaxial compression devices with various fracture criteria by the magnitude of relative deformation are also given. Taking into account the recommendations set out in the article will help prevent the development of emergency situations during the construction of facilities on sandy soils.
    Keywords: geotechnical risks, sandy foundations of structures, sandy soils, deformations of structures, soil liquefaction, laboratory and field tests.
