Numerical and experimental investigation of the cave passage model

A novel approach to reinforcing the soil structures of historical underground sites, such as those found at Kyiv-Pechersk Lavra, has been demonstrated through combined numerical and experimental investigations. The study reveals that integrating basalt reinforcement—specifically flat frames and individual rods—into damaged soil layers significantly enhances structural stability under high humidity and aggressive environmental conditions. This method was validated using a full-scale model of the Far Caves' underground passage, tested over eight years at the Kyiv National University of Construction and Architecture. The findings suggest that this technique can restore the original state of historical structures while ensuring long-term functionality, offering a practical solution for preserving UNESCO World Heritage Sites with similar geological challenges.
