【Abstract】 Prestressed cable has been widely used in geotechnical engineering; and many achievements of its anchoring effect have been obtained. For examining those achievements and gaining further conclusions about anchoring effect of prestressed cable, indoor large-scale simulation test has been made. Based on the results from the simulation test, a mechanical model for numerical simulation is established. Further analysis of anchoring effect of prestressed cable is put forward using numerical simulation, Finally, some important and practical conclusions have been drawn.更多还原
