| Abstract: | Based on the reasonable model of soil-underground structure, the paper analyses the stress and displacement of underground structures and displacement of soil layers subjected to earthquakes occurring directly beneath the structure by the finite element method. In addition, the effect of seismic force to the underground structure is studied. The results show that the vertical seismic force improves the dynamic reaction of structure. Moreover, vertical earthquake force plays an important role in damage of underground structures. |
