Review on mechanical response of anchored fractured rock mass under freeze-thaw action
There is a significant difference between the mechanical response of anchored rock mass and that of fractured rock mass under freeze-thaw cycles.It is of great significance to study the mechanical response of anchored rock mass to the long-term safety control of anchored slope in cold area.Based on the research of freeze-thaw response of fractured rock mass,the research progress of mechanical response behavior of fractured rock mass anchored in fractured slope under freeze-thaw cycle was reviewed in this paper.The research results of mechanical response of anchored rock mass to freeze-thaw action were summarized from the aspects of frost heave force of crack and prestress of anchorage structure.The development trend of research on freeze-thaw mechanical response of anchored rock mass was prospected,and the evolution law of freeze-heave force and anchorage force in anchored rock mass under freeze-thaw condition was the focus of further research.
