Dynamic response and stability analysis of deep excavation engineering under seismic loading

Deep excavation engineering plays a crucial role in modern urban construction, and its safety has garnered significant attention, especially in seismically active regions. The complex structure and scale of deep excavations make the study of their dynamic response and stability under seismic loading particularly important. However, current research on deep excavation engineering under seismic effects has certain limitations, primarily in the insufficient consideration of the interaction between excavation structures and the surrounding soil, as well as the inaccuracy of seismic load simulations. These limitations restrict the effectiveness and accuracy of existing design theories. This study aims to explore the dynamic response and stability issues of deep excavation engineering under seismic loading in depth. The research focuses on two main aspects: first, investigating the dynamic response characteristics of deep excavations under different seismic conditions; and second, evaluating the overall stability of deep excavations under seismic loading using stability analysis models. Through a systematic study, this research aims to provide a theoretical basis and technical support for the seismic design of deep excavation engineering, ultimately enhancing safety in engineering practice.
