Abstract

With the acceleration of urbanization, the scale of urban underground space development is expanding day by day, and the seismic safety of underground structures such as subway stations and underground parking lots has become the focus of research in the field of civil engineering. Under the action of earthquakes, underground structures are faced with complex dynamic response and failure risks, and their seismic design needs to comprehensively consider the coupling effects of multiple factors such as seismic wave propagation characteristics, soil-structure interaction and structural form. Focusing on the theory, method and damping technology of seismic design of underground space structures, this paper provides theoretical support and practical reference for improving the seismic performance of underground structures by combing the research status at home and abroad, analyzing the technical limitations and looking forward to the development trend. Specifically, the content covers the force characteristics, design methods, seismic absorption measures and engineering cases, aiming to reveal the key scientific problems and technical challenges of seismic design of underground structures.
