Abstract:

With the acceleration of urbanization, the distance between the underground structure and the aboveground structure is becoming smaller and smaller, and the mutual influence between them during earthquake is worthy of attention. In this study, a three-dimensional (3D) finite element (FE) analysis procedure was verified based on shaking table test data firstly. Subsequently, the validated FE analysis procedure was used to carry out an extended parameter analysis to study general seismic response of more complex aboveground structure-soil-underground structure systems. The key parameters, such as the height and number of aboveground structures, earthquake type, and distance between underground and aboveground structures, were considered. It was found that the tunnel-soil-aboveground structure interaction could effectively affect the acceleration and deformation response of both the ground and underground structures. With the increasing height and number of aboveground structures and the decreasing distance between underground and aboveground structures, the deformation of the underground structure tended to become larger. On the other hand, the existence of underground structure could effectively reduce the response of aboveground structure, and the influencing effect was found to be considerably affected by the distance between underground and aboveground structures. The findings obtained from this study could provide useful references for the seismic design of both aboveground and underground structures in urban areas.
