Preliminary Design of Retrofitted System of Domestic Subway Tunnel
도시철도 개착식 터널의 내진성능보강시스템 기본설계
Abstract
The occurrence rate of the earthquake more than magnitude 5 has been increased since 1990 and the damage of the Odaesan earthquake, 2007 was serious. Due to that, one may say that Korea is not any more safe for the earthquake. Therefore, it is necessary to prepare strategies for possible damage due to strong earthquakes in future. This study is to focus to develop the retrofitting system for the cut and cuver tunnels built without earthquake type load scenario, so that it can provide the safety of existing urban subway system against earthquakes.
