Barrier-based ground vibration mitigation: a state-of-the-art review
摘要
Barrier-based ground vibration mitigation has been extensively investigated over the past seven decades as an effective means of protecting structures from machine, traffic, and railway-induced vibrations. This state-of-the-art review presents a systematic synthesis of experimental, numerical, and analytical studies on vibration isolation using trenches, piles, wave impeding blocks, and emerging periodic and metamaterial-based barriers. The influence of key governing parameters, including excitation frequency, acoustic impedance ratio, shear wave velocity, material density, groundwater table, and geometric configurations, is critically analysed. Particular emphasis is placed on the comparative performance of various infill materials, including geofoam, sand- crumb rubber mixtures, soil-bentonite, bamboo, and composite systems. Recent advances involving artificial intelligence, geosynthetics, multiple-barrier configurations, and metamaterial-assisted designs are comprehensively reviewed. By consolidating fragmented findings and identifying consistent trends, unresolved challenges, and research gaps, this paper provides practical design insights and future research directions for developing efficient, sustainable, and frequency-targeted vibration mitigation systems.
