摘要

The rise in urbanization and industrial activities is driving a rapid increase in the generation of ground-borne vibrations. These unavoidable ground-borne vibrations resulting from machine foundations are very common and can cause public nuisances and damage to the surrounding buildings. Significant research has been conducted to isolate these unwanted vibrations using single barriers filled with conventional materials. However, the conventional material-filled single barriers underperform significantly relative to the open barriers. Therefore, these single barriers require significant depth to cater to the vibration mitigation demand. The current study aims to summarize the experimental and numerical findings from past studies related to geosynthetic-based dual barrier systems, which are known for reducing depth requirements. Geofoam was found to be the most preferred type of geosynthetics for infilling the barrier systems. The findings showed that the geofoam-filled dual barriers screened 40% more vibrations compared to the geofoam-filled single barrier. Also, the isolation capabilities of geofoam-filled dual barriers were up to 1600% higher compared to the dual barriers filled with conventional materials.
