시뮬레이션을 통한 도로터널내 피난연락갱 설치간격에 관한 연구

It is very important to evacuate a tunnel in emergency situation such as fire. There are variable factor in which are ventilation, emergency system. But, it is necessary to predict that is proper evacuation circumstance in most critical situation that is not to operate tunnel ventilation system such as a breakdown, and will be offered proper design(Equipment, structure for evacuation, etc). This study has performed to compare required evacuation time in emergency situation with variable distance of the cross-passage by computer simulation test.
