Abstract：
Having a section that passes through a fault is one vulnerability regarding the seismic resistance of a tunnel. Based on the Ya'an-Lugu expressway tunnel in an area of southwest China characterized by high seismic intensity, an experimental study using a shaking table model for tunnels passing through faults was conducted, which determined the similarity relation of the model systems according to test conditions and the shaking table performance. Then, similar materials were finalized through indoor ratio tests, and the model casing was designed according to testing characteristics. The "model casing effects" were analyzed and handled, and a reasonable layout of sensors was carried out as per numerical calculation results. Finally, the test conditions were designed according to the test intentions.
