Outline of Final Research Achievements

Coastal railways are important facilities that support logistics and living in Japan. This study experimentally reproduced the deformation of the embankment and track bed of coastal railways due to high waves to reveal the mechanism for causing damage. Specific measures that can be adopted on-site were also presented based on the spraying characteristics of splash overtopping that hinders the safe railway operation and the movement characteristics of the track bed ballast due to wave overtopping that may cause derailment. The study also enabled evaluation of the hazard level depending on the track installation conditions by presenting a method for calculating the tsunami force that acts on railway bridges and cars.
