Ground Vibration Characteristics Induced at High-Speed by Shinkansen and Evaluation Method for Speed Dependency

This article provides general research into the effects of the increasing speeds of Japan's high-speed Shinkansen railway on ground vibration. In order to offer an adequate assessment model, the authors propose a velocity law that incorporates the vibration level caused by the Shinkansen with the train's speed. In order to determine the levels of vibration, researchers conducted two high-speed tests on different lines and with different railcars. The predictive power of the proposed model relies on the average thickness of the ground on which the rail lies coupled with the discovered speed power exponent, which then allows for ground vibration to be calculated using simple spreadsheet software. Researchers determined that a low-frequency 4 Hz is dominant for trains over 300 kilometers per hour.
