  • Vibration of a segment tunnel lining under internal blast

    Vibration of a segment tunnel lining under internal blast

    Segmental tunnel is common in subway tunnel engineering which is at risk of being attacked by terrorists bombing and accidental explosions. Due to the discreteness of segmental tunnel lining its difficult to model its dynamic response to internal blast loading. In this paper a simplified equivalent model was proposed to model the segmental tunnel linings vibration response to.
