Review and Future of Research and Development in Railway Disaster Preventions Against Natural Hazard


Katsuya OKADA
Many railway lines in Japan constructed across rapid stream rivers and along unstable slopes suffer from various disasters caused by earthquake, flood, heavy rainfall,tremendous snowfall,frost, strong wind,etc. This paper is a review of research and developments for railway disaster preventions against such natural hazards. The review covers the earthquake damage to soil structures, scouring around the pier in flood, heavy rainfall causing slope failures, snowfall damage to railway structures and cars, frost-heave in tunnels and track formation, and strong wind disrupting the railaway operations. The future perspective in railway disaster preventions is also discussed.
