Abstract
Rock excavation has been the hot spot and frontier of scientific research. Rock excavation research is in a period of rapid development. The bibliographies included in ISI Web of Knowledge database from 1999–2020 were used as data samples, and the collected data were analyzed by literature co-citation and cluster analysis using CiteSpace and VOSviewer information visualization techniques and dynamic network analysis tools. A knowledge map of the evolution of bibliometric research development is drawn to reveal the representative literature in the field of bibliometrics. The hot areas of bibliometric research are introduced. The development trend of bibliometrics is proposed. The results of the study show that the amount of the literature on rock excavation is growing rapidly. A large amount of the foreign literature is available in China, the United States, Australia, Canada, France, and other countries. The main included journals are Tunnelling and Underground Space Technology, International Journal of Rock Mechanics and Mining Sciences, “Rock Mechanics and Rock Engineering,” “Engineering Geology,” and “Bulletin of Engineering Geology and the Environment.” Keyword co-occurrence analysis includes the following contents: rock damage constitutive model, excavation damage area, numerical simulation, stability analysis support, and prediction technology of rock.
Highlights
With the rapid development of underground engineering, many theories and techniques on effective rock breaking have emerged
CiteSpace software at different levels, and the study came to the following conclusions: (1) The temporal distribution spectrum shows that rock excavation research has great value, the number of research papers was relatively stable from 1999 to
2010, but research began to emerge centrally after and entered a large-scale, rapid development phase in 2018∼2020 and received widespread attention; the number of research results is abundant, and the overall trend of increasing development is on the rise, and the future expects more researchers’
Summary
With the rapid development of underground engineering, many theories and techniques on effective rock breaking have emerged. There are many methods of literature research; among which scientometrics and informatics technologies have been rapidly developed in recent years, providing a reliable way for the research of the thesis data visualization. These methods make up for the shortcomings of traditional literature review research, such as insufficient reference literature and weak objective performance. Compared with the traditional research method of the review literature with reading, summary, and qualitative discussion as the main process, knowledge graph software has the advantages of large volume of literature processing, intuitive visualization, diverse analysis angles, and high reliability of data analysis results. Most of the first scholars in China who conducted research on the application of the knowledge graph came from the information intelligence field and university libraries and other institutions
