Abstract

Based on the Natural Science Foundation Project of China “Theoretical study on shock absorption of tunnel subjected to near-fault pulse-like ground motions” (51078324), this research conducts a shaking table model test scheme study to explore the seismic responses of tunnel subjected to near-fault pulse-like ground motions. The test which includes the decision of model similarity ratio, the design of model box and the treatment of boundary, the making of model, the layout of test points and the loading scheme of seismic wave and so on is introduced in detail in this paper. The test focuses on the rule and character of the dynamic response of the tunnel subjected to near-fault pulse-like ground motions. The test results show that the near-fault pulse-like ground motions is destructive. With seismic waves upward propagating, the seismic response of rock and soil is increasing. The tunnel linings were severely damaged.
