Abstract: ABSTRACT: Mountain tunnels are sometimes subject to deformation caused by post-construction earth pressure. Defects such as cracks, or deformation of tunnel lining may occur depending on the structural properties of the tunnel or surrounding geological characteristics. In such cases, countermeasures for tunnels in service need to be carried out against earth pressure. This paper outlines the...
Abstract: If a large amount of water inflow occurs suddenly during the construction of a mountain tunnel, it may lead to a deterioration of construction performance and collapse of the tunnel face. In addition, it is expected that the ground water inflow will have a significant impact on the living environment of the neighboring residents at the tunnel construction site in the case of a small overburden....
