Abstract

Dynamic behaviour of diverse footings resting on saturated sand filled in a large model groove was investigated. The vibration parameters include the frequency and waveform, which were related to the footing height, shape, stiffness, and embedment. A vertical-vibration attenuation equation for saturated sand was proposed. Experiments on the dynamic response of the footings resting on geogrid-reinforced saturated sand were carried out in terms of the geogrid layers, burial depth, and geogrid area. The results show that, the velocity amplitude increases with an increase in the frequency from 0 to 27 Hz and is maximum at the resonant frequency. Moreover, the vertical velocity for a rectangular footing is the highest among three different footing models. Increases in the footing stiffness and footing height lead to a beneficial reduction in the dynamic response, and the vibration velocity increases with an increase in the footing embedment in sandy soil. In addition, the vertical velocity reduces with the increase in the number of geogrid layers, and with the increases in the geogrid area and burial depth.
