Ground vibration isolation using mass scatters: A comparative study with trench barriers and wave‐impeding blocks

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 792-799, December 2025.
Ground‐borne vibrations are a frequent source of environmental problems. A full‐scale experiment is conducted to validate a 3D numerical model in order to analyze the efficiency of three methods of isolation. Trench barriers and wave‐impeding blocks are impractical and expensive methods of isolation, but mass scatters appear to be an efficient ...
