Abstract

Using shaking table model tests, the accuracy of the evaluation method for damping layer and the interaction between the lining structure and grade IV as well grade V surrounding rock with seismic excitation were researched, which were the most adverse surrounding rock condition. The results show that: the evaluation method can accurately assess the seismic effect of damping layer acting on lining structure, but the test value will deviate from the evaluation value with the increase of peak excitation acceleration. Therefore, a seismic reduction coefficient is introduced to improve the precision of the evaluation method. Further, the grade of surrounding rock plays a more decisive role than the thickness of the damping layer in the seismic response of the lining structure. Besides, in the medium and low-intensity earthquake zones, the protective effect of the damping layer is obvious, but the damping layer has an optimal thickness, beyond which the vibration of the lining structure will be more acute. In terms of the high-intensity earthquake zones, the difference in the protective effect of damping layer is no longer obvious. In addition, damping layer changes the vibration characteristic of lining structure, it creates a rigid displacement margin between the lining structure and surrounding rock, which can reduce the maximum relative displacement with seismic excitation.
