Abstract
The current metro systems have become an important part of the public transport system inmajor cities around the world. With the development of construction technology as well as technicalrequirements, the segmental tunnel lining has become the main lining used protective for tunnels. The maineffect of segmental tunnel lining when it is used for tunnels that is ability strengthened stability of tunnelsunder the impact of earthquakes. This paper presents methods for calculating to effects of earthquakes ontunnels lining in two cases: tunnel continuous lining and segmental tunnel lining by identifying internal forcespresent on tunnels lining and the deformation of tunnels lining. Based on results obtained, analysis the effectof the joints for segmental tunnel lining under seismic loads and the effect of the rotation stiffness of joints tothe segmental tunnel lining when have got the impact of earthquakes to the tunnel. This paper used parametersof the tunnel in Hanoi metro system as a case study.
