Description
lt is necessary to predict the influence of the surrounding ground and tunnel during the excavation of twin tunnel. Usually, the influence of the excavation patterns and the efftct of the interaction between the ground and existing structures are not taken into account. In this research, using a new tunnel device in which a hybrid type boundary condition is applied at the excavation face to determine inner displacement and stress at the tunnel periphery, model tests on tunnel excavation are carried out. Non-linear finite element analyses are also conducted with the same scale of the model tests. It is revealed that building loads, the earth pressure distribution and ground movements during tunnel excavation depends on the distance between the twin tunnels.
