Dynamic response analysis of underground structures is a key research topic in structural dynamic analysis in recent years, which plays a very important role in engineering construction. Three-dimensional dynamic model is established by large-scale finite element program, and the structure is modified by design parameter model modification method based on sensitivity analysis. The basic finite element model of the structure is established, and the deformation and internal force response of the structure are obtained. The inter-story displacement difference, inter-story displacement angle and static and dynamic mechanical characteristics of the structure are analyzed. Explore the use of elastic boundary element between soil and structure to carry out seismic analysis of structures; Compared with the same structure without elastic boundary element, it is very necessary to calculate the earthquake resistance of underground structure.
