Seismic safety of underground structures is of paramount importance. This paper reviews the current research status of seismic response analysis methods for underground structures, focuses on the basic principles, advantages and disadvantages, and applicability of the proposed static method and dynamic time course analysis method. It also analyses their applications in engineering. It is shown that the seismic coefficient method, although simple, may have relatively large calculation errors due to oversimplification. The free-field deformation method is simple in form and easy to implement, but ignores soil-structure interaction. The flexibility coefficient method is simple in form and considers soil-structure interaction, but ignores many factors. The reaction displacement method directly reflects the soil-structure interaction, but the foundation spring parameters are difficult to value. The reaction acceleration method has the same advantages as the reaction displacement method, but there is a certain error. The dynamic time-course analysis method is accurate but computationally intensive.
