減災に向けたこれからの研究開発

摘要

In Japan, the disaster prevention technology in railway has been developed by many disaster experiences since the beginning of its operation. It was reported various parts of Japan suffered by an earthquake, some heavy rains and other aspects, last year, however, the damage of railway was found to be minimized fortunately. This result obviously demonstrates the past developments on the disaster prevention technology. On the other hand, the level of natural forces bring disaster has become slightly larger, and the further progress of the damage estimation technology that accepts the changing of natural forces is expected for the future railway disaster prevention. This paper describes the recent state and the future prospects of the research and development on the disaster prevention in the Railway Technical Research Institute.%鉄道における災害発生件数は減少傾向にあるが，最近では，地球温暖化の影響もあって気象状況そのものが変化しつつあり，これに伴う新たな形態の災害も見られるようになっていることは，既に幾つかの紙面で指摘してきた。また，昨年の東北地方太平洋沖地震では，沿岸域において津波による甚大な被害を受けた。こうしたなか，鉄道総研では幅広い視点からさまざまな種類の災害防止?減災に向けた研究開発に取り組んでいる。
