Abstract:A new method of equivalent pre-stress is suggested by used of methods of equivalent strain and temperature according to different working mechanisms between free segment and consolidated segment of pre-stress anchor cable. The mechanism on reinforcement of pre stress anchor cable is simulated by finite element. Due to enhanced toughness and anti-crack of root effect, anchor cables restrained the rock mass deforming toward surface. Rock mass around consolidated segment sustain tension. The anchor cable of unequ… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
