ABSTRACT

Due to the industrialization and overpopulation of cities, the facilities become bigger and taller and underground common use spaces such as subway, underground passages and tunnels are gradually expanding through the development of deep excavation technology. In the event of a collapse accident, huge damage may occur. When a collapse accident occurs, the member of framework supporting the buried void will be damaged as a result of initial collapse, showing unstable movements in comparison to their stable conditions. Therefore, the safety assessment of the support structure for void is essential in order to rescue a person isolated in the collapsed area. This study develops a numerical model that analyzes the support type for void in the buried area depending on cause of collapse and performs safety assessment of void in the buried area against a vibration that may occur at the time of excavation.
