A full experimental and numerical modelling of the practicability of thin foam barrier as vibration reduction measure

This paper investigates the effectiveness of geofoam-filled barriers in isolating ground vibrations caused by harmonic loads, comparing single, double, and triangle wall configurations. A 3D finite element model (Plaxis) was used for analysis, validated against analytical solutions, and optimized through genetic algorithms to enhance vibration attenuation efficiency. Results indicate that double wall systems are most effective across varying frequencies, while geometric parameters significantly influence overall performance.
