中文摘要：

大量工程实践表明，隧道跨断层段是隧道抗震的薄弱环节。文章以西南高烈度地震区雅泸高速公路隧道为背景，对跨断层隧道抗减震振动台模型进行了试验方案研究。首先根据试验条件和振动台性能，确定模型系统的相似关系，并通过室内配比试验确定相似材料；同时根据试验特点，设计了模型箱，并对“模型箱效应”进行了分析和处理，然后根据跨断层隧道的数值计算结果，对传感器布置进行优化设计；最后确定地震输入加速度和加载方案。

英文摘要：

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 lay- out of sensors was carried out as per numerical calculation results. Finally, the test conditions were designed ac- cording to the test intentions.
