Abstract
When we construct a building near the railway tracks, it is often necessary to predict the level of vibration and structure-borne sound induced in the building. Therefore, we investigated the property of vibration propagation from the ground to the pile-foundations based on vibration tests with a soil-pile interaction model including a footing-beam, and predicted the property of vibration propagation with a simple prediction method based on the dynamic-substructure method. Furthermore, we predicted the vibration propagation from the ground to the pile-foundations of two buildings, of which the one was located near the tracks on the ground and the other near the viaduct, and confirmed that the predicted results were similar to the measurements. Finally, we discussed the effect of a vibration insulation method for footing-beams based on the prediction method.
