Abstract: The large-diameter recoverable anchor has many notable advantages, including good load-bearing capacity and economic benefits, thus it will have good application prospect in excavation and slope engineering. Based on the FEM, the bearing and deformation behaviours of large-diameter recoverable anchors are analyzed. The results indicate that the bearing and deformation behaviors of large-diameter recoverable anchors have a close relation with those of bonding segments. The ultimate bearing capacity increases with the growth of the length and diameter of bonding segments, and when horizontal angle of bonding segments is between 15癮nd 35?, the anchors have better behaviours. These results may provide reference for some projects.
