Application and Research Status of Tunnel Type Anchorage Based on Literature Statistics

Based on the important literature databases at home and abroad, using literature measurement technology, this paper sorted out and improved the application status of tunnel type anchorages inside and outside the project, analyzed the characteristics of 30 tunnel type anchorages, such as construction location, application quantity, main span, axial length of anchorage plug body and surrounding rock properties, and speculated the future trend of tunnel anchorage construction. By means of literature statistics, the selection of tunnel type anchorage materials and structures is summarized, this paper investigates the publication of relevant Chinese and English papers on tunnel anchorage at home and abroad in the past 20 years, counts the literature source journals and Dissertations of tunnel anchorage, analyzes the publishing institutions of relevant papers, constructs a keyword co-occurrence network by using visualization technology, and sorts out the current research hotspots and emphases of tunnel anchorage. Based on the above research status of tunnel anchorage, this paper puts forward brief thoughts on the future research direction of tunnel anchorage, and believes that the application of tunnel anchorage will be more extensive, and more in-depth and comprehensive research on complex geology is also needed.
