Bibliometric and visual analysis on research of freeze-thaw of rock slopes based on CNKI Data

Abstract

In order to explore the research status of rock slope freeze-thaw problems, 228 domestic and foreign rock slope freeze_x005fthaw papers were retrieved as the samples based on the CNKI database. CiteSpace was used to conduct bibliometric and knowledge map analysis on the number of paper publications, authors, and keywords. The results show that the annual publication volume in this fi eld are generally increasing, indicating a large development space in future. There are many research teams and institutions in this fi eld, but there is less collaboration between diff erent teams. According to the timeline map, revealing that earlier literature focused mainly on understanding and prevention of rock slope freeze-thaw problems. New technologies from other fi elds have been gradually applied for innovation in recent years. The future research trend will involve micro-damage, multi-fi eld coupling, dynamic responses, monitoring and warning of rock slope freeze-thaw problems.
