Abstract: Based on the background of a complex tunnel constructed in Tibet, a large-scale shaking table test is accomplished to study the seismic responses of the tunnel through fault. The paper introduces the test including the decision of model similarity ratio, the design of model box and the treatment of boundary, the making of model, the layout of monitored points and the input scheme of seismic wave and so on. The test focuses on the rule and character of the dynamic response of the tunnel through fault. From the test, it is concluded that there are some similarities in seismic response between the tunnel through fault and the tunnel through homogeneous rock. With seismic wave upward propagating, seismic response of rock and soil is increasing and the tunnel lining in fault is damaged severely. There is a certain influence on seismic wave propagation because of fault.

Key words: fault, tunnel, shaking table, model test
