Abstract: In order to explore the current research and development status of tunnel intelligent construction technology and accelerate its innovation, this paper adopts a multi-dimensional patent technology hotspot identification method based on the BERTopic topic model to analyze the research and development trends of global patents related to tunnel intelligent construction technology. An innovative two-dimensional technical topic analysis of "professional technology-information technology" is applied. The study analyzes the research hotspots of tunnel intelligent construction technology based on patents in the field, and analyzes the overall technology-effectiveness layout of global tunnel intelligent construction-related patents in conjunction with the patent technology-effectiveness matrix. The research identifies current technical hotspots and gaps in the field of tunnel intelligent construction, clarifying the future de? velopment trends of tunnel intelligent construction technology. It also provides suggestions for the development of tunnel intelligent construction technology in China. The results indicate that there is still significant room for development in areas such as surrounding rock determination, auxiliary equipment, anchor bolt drilling, operational management, and tunnel blasting in China. There is a need to accelerate the research and development of related key technologies and optimize the corresponding patent layout.
