Abstract

This study aims to investigate the vibration response of the foundation soil under impact loading through model experiments and to analyze the influence of the rubber vibration-isolation layer on the dynamic response of the soil. Based on actual engineering conditions as the reference prototype for the experiments, a concrete foundation model was designed, and accelerometers were reasonably arranged. Impact loading was applied by dropping a weight from a certain height. By comparing the data from two sets of experiments with and without the vibration-isolation layer, the influence of the vibration-isolation layer on the vibration response of the soil was revealed.
