英文摘要：Sudden loading events pose a serious threat to the structural safety of shield tunnels, which may lead to tunnel deformation, cracking, and even collapse. By summarizing and organizing engineering cases, the research results on deformation control measures for existing shield tunnels under sudden loading at home and abroad were sorted out. Common reinforcement measures were summarized and their frequency and effectiveness were analyzed. Classify the existing control measures into two categories: active control and passive control. and passive control, and the mechanism and application effect of these control measures are analyzed. Finally, the shortcomings of existing research were pointed out, and future research directions were proposed, including the development of refined theoretical models, improvement of experiments and simulations, construction of data systems, and exploration of new reinforcement technologies.
