Investigation of soil conditions in a selected section of a railway cut as a basis for designing geoengineering works to improve their geotechnical parameters

Abstract

One approach to enabling construction, engineering, and mining activities in subsoil with insufficient geo-mechanical properties is to employ innovative methods and technologies. These can effectively modify the physical and mechanical characteristics of the subsoil. The article explores engineering techniques that can enhance the geotechnical properties of soils in locations where they exhibit dysfunctions, such as reduced stability and bearing capacity. Additionally, the paper emphasizes the importance of conducting specific geo-engineering tests to accurately assess the geotechnical conditions. The research directly evaluates the stability of a railway section within the Western Carpathians and presents findings from both field and laboratory tests. Given the instability observed in this section, there is a pressing need for geo-engineering reinforcement measures. These efforts aim to enhance the geotechnical properties and safeguard the railway embankment from potential landslides. Detailed accounts of these remedial works will be the focus of a subsequent study.
