Abstract: Dynamic time history analysis method is widely regarded as the most accurate calculation of the theoretical seismic analysis of structures. The paper analyzes the response of underground construction close to the building with the three strong waves focused on it,and the two propagation directions are compared during the process in order to ensure the underground structures safe,reliable. Besides,a three-dimensional underground garage,underground garage foundation and surrounding soil model are established with limited use of common space element analysis software,meanwhile,the friction of pile-soil contact time-history analysis of seismic waves is taken into consideration. The paper,especially studies the impact of seismic wave propagation in the vertical direction of underground structures,and verifies the effects of pile-soil seismic response. All of the studies will provide a further reference for the similar projects.
