| Title of the article | Changes in the parameters of the stress-strain state of sand foundations exposed to technogenic pollution |
| Abstract. | Contamination of soils with oil products has a negative effect not only on the fertile properties of soils and grounds, but also leads to a decrease in their strength characteristics necessary for the design of foundations and bases. The purpose of the work is to analyze changes in the parameters of the stress-strain state of sand foundations exposed to technogenic pollution. The tasks of the research are laboratory studies of changes in specific adhesion and the angle of internal friction, taking into account a number of variable parameters, such as sand size, type of oil product and its concentration, as well as the analysis of changes in the value of the design resistance and ultimate pressure based on the obtained laboratory data. The paper presents experimentally established patterns of changes in the strength characteristics of sandy soils when interacting with various types of oil products, and also substantiates a reduction in the design resistance by 10-38% and the ultimate pressure on the foundation soil by 17-60% depending on the size of the sand, the type of oil product and its concentration. The significance of the results obtained for the construction industry lies in the possibility of their application in developing recommendations for geotechnical calculations. |
