In recent years, large-scale buildings that require quietness are increasingly built close to railways, to make it indispensable to precisely predict railway vibration and structure-borne sound. For this purpose, it is required to assess the properties of the vibration caused by train running to propagate to buildings during the course of construction work. This will also contribute to the verification of predicted results. For two SRC buildings (vibration proof and base-isolated) built in a compound that is sandwiched by a surface transit railway line and a subway line, we measured the vibration propagation properties to these buildings at different stages of construction work and assessed the effect to prevent ground-foundation vibration. We also grasped the result of numerical analysis (FEM) for railway-induced vibration of the building structure with base-isolation.
