A Study on Propagation Properties of Vibration With Tunnel-Soil-Frame Interaction Model Test

In order to predict the level of vibration and structure-borne sound of a building near the underground railway tracks, it is essential to investigate vibration propagation from the ground to the foundation of the building. Therefore, the authors proposed a simple prediction method of vibration propagation from the ground to pile-foundations based on the dynamic-substructure method, which was able to consider the soil-structure-interaction. In the method, input vibration to pile-foundations and response ratio of upper-structures with the dynamic-soil-spring were calculated. We predicted the vibration propagation from the tunnel to the buildings of three types, and confirmed that the predicted results were similar to the measurements.

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.
