Project Information
In 2021, Caucasus Science and Engineering (CSE), in cooperation with SSF Ingenieure AG and on behalf of Caucasus Road Project (CRP), undertook a preliminary design study for the stabilization of the Mskhaldidi landslide in Georgia’s Mtskheta-Mtianeti region. This critical slope failure, involving nearly 20,000 m³ of displaced material, had repeatedly reactivated during heavy rainfall, threatening local infrastructure and forcing road closures. CSE’s team carried out a detailed geotechnical investigation program including engineering geological mapping, UAV drone surveys, structural measurements, drilling campaigns, and seismic and hydrological studies. These investigations confirmed that the landslide developed along weak claystone bedding planes in highly unfavorable “dip slope” conditions, with shallow deformations occurring close to the road level. Based on this analysis, a comprehensive mitigation concept was prepared. Key measures included a back-anchored retaining wall with micropile foundations to secure the road, high-strength steel mesh and soil nails to stabilize exposed slopes, and strategic backfilling to restore original topography. A robust drainage system was also proposed to control precipitation and runoff, complemented by a long-term monitoring plan with inclinometers and observation-based construction methods in line with Eurocode 7 standards. This project illustrates CSE’s expertise in managing complex landslide conditions in mountainous terrain. By integrating advanced geotechnical analysis with practical engineering design, CSE delivered a feasible and resilient stabilization strategy, ensuring safer road infrastructure and long-term slope stability in one of Georgia’s most geologically challenging areas.
