A study of open cut box curvert tunnel strengthening systems in domestic underground railway

도시철도 개착식 터널의 내진성능보강시스템 개발에 대한 연구

There are execute of new laws about prevent of earthquake diaster in nation because of some increments of big earthquake occurence frequency. Now develope new composit plate by ductile fiber with strong mechanic materials, which compose of strengthening systems for the underground structures subject to forced displacements. 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.
