Strength properties of saline soils of earthworks in conditions of flooding

Abstract

The article "Strength properties of saline soils of earthworks in conditions of flooding" examines the change in strength characteristics of soils subjected to salinization in conditions of partial or complete flooding. The relevance of the study is due to the fact that many regions face problems related to changes in the groundwater level, which negatively affects the stability of earthworks. The paper presents the results of experimental studies showing how the presence of salts in the soil affects its mechanical properties.  Various types of salts and their concentrations are investigated, as well as the conditions under which the soil is most sensitive to changes in strength characteristics. In particular, special attention is paid to the interaction of salts with water and changes in the structure of the soil, which can lead to a decrease in the strength and stability of structures. Practical recommendations on the design and strengthening of earthworks on saline and flooded lands are also discussed. In conclusion, the need to take into account the strength properties of saline soils when planning construction works and creating flood protection systems is emphasized, which is important to ensure the strength and safety of infrastructure.
