A damaged railway line in Astana, Kazakhstan, which is located on soft soil, is the subject of an investigation, and possible remedial options are discussed in this paper. We conducted an analysis and geotechnical investigation using modern soft soil improvement techniques to identify the most effective strategies for stabilizing the damaged subgrade and to suggest remedial actions. The methods and procedures for stabilizing the soft soil were selected taking into account the need to ensure uninterrupted train traffic on the line, the largest equipment that could be used on the site, and the height restrictions imposed by overhead power lines. It was proposed to use vertical and horizontal micropiles for reinforcement to ensure the stability and reliability of the railway track. Recommendations for the restoration of the soft soil beneath the damaged section of the railway line, derived from the geotechnical investigations, are presented and illustrated in this paper. Understanding the relationship between soil and structure on problematic soft soils has been made possible by these studies.
