Abstract

To investigate the influence of structural form on the vibration reduction and isolation effect of soilbag foundations, a series of small shake table model tests were conducted. The influential factors primarily consisted of the peak ground acceleration (PGA) of the input motion, the arrangement form of the soilbag foundation, the retaining structure, and the interspace between adjacent soilbags. Test results demonstrate that a higher PGA yields a greater impact on the vibration reduction and isolation of soilbag foundations, irrespective of the arrangement form. By comparing the acceleration response within model foundations featuring different soilbag arrangement forms, we found that the interlaced soilbag foundation exhibited a significant effect on the attenuation of vibration waves. Furthermore, the presence of a retaining structure within the foundation trench effectively enhances the vibration reduction and isolation effect of soilbag foundations, and also prevents the surrounding soil from falling into the interspace between soilbags. Additionally, maintaining an appropriate interspace between soilbags proved to be advantageous in maximizing the benefits of vibration reduction and isolation in soilbag foundations.
