Abstract: The elastic-flexible anchor is a new type anchor which added a elastic-flexible deformable body on the common anchor.Through developing the comparing numerical simulation analysis between the common anchor and the elastic-flexible anchor by the FLAC,we confirmed that,due to the buffering effect of the stress and deformation in the elastic-flexible deformable body,the elastic-flexible anchor has the higher bearing capacity and more excellent anti-deformation performance,especially applied to the support structure with the requirements of large deformation and dynamic load,and worth popularizing in the anchor retaining wall engineering.
