摘要：
The dynamic response of an underground-commercial-street structure subjected to different types of seismic waves and corresponding influence factors are studied. Based on a monolayer underground- commercial-street structure, the three-dimensional finite element model with three-dimensional equivalent viscoelastic boundary element of a soil-underground structure-interaction system is established, then the structural dynamic response is calculated with different types of seismic excitations, and the effect of buried depth, soil stiffness, and seismic input types are discussed. The results indicate that: for the seismic response of such underground structure, there is most unfavorable buried depth; soil stiffness has a significant impact; seismic response value under long-period seismic waves is significantly larger than that under ordinary seismic waves. © 2016, Engineering Mechanics Press.
