ENGINEERING GEOLOGICAL ANALYSIS OF THE LANDSLIDE CAUSES DURING THE CONSTRUCTION OF INDUSTRIAL BUILDING

The construction of industrial buildings near the slopes is associated with the risk of landslide development which may threaten the normal functioning of such structures. Slope stability prediction is a complex task the successful solution of which is due to the correct choice of the design scheme and its parameters. Analysis of landslide causes allows geotechnical engineers to identify and correct errors made in the design, thereby increasing the reliability of the calculations made. This article discusses a landslide that occurred during the construction of an industrial structure in the area of widespread swelling soils. The features of geological structure and soil properties, obtained on the basis of a large amount of experimental data, were analyzed. Particular attention is paid to shear strength parameters of soils in the conditions of their swelling. It is shown that soils are sensitive with additional moisture. According to the field and laboratory studies as well as the reverse calculation of the slope stability, the shear strength parameters of soils were adjusted. The recommendations to improve the stability of the slope were given.
