Abstract: Anchoring is an important reinforcement in the geotechnical engineering. At the same time, the shotcreting is always indispensable for an anchoring engineering; so a reasonable thickness of the shotcrete and an anchoring parameter are very important for designing reinforcement engineering. Based on the theory of plate bending and considering the interaction of the shotcrete and anchor, it is concluded that the S-shape of the steel net is the most suitable. For example, based on the finite difference simulation of FLAC, the mechanism and effectiveness of the shotcrete in the reinforced earth retaining wall has been studied; the result shows that the shotcrete is effective in controlling the surface displacement of the wall, in deducing the plastic failure of the wall foot, in reducing the lose of the prestress of the anchors, and in improving the effectiveness of the reinforcement. At the same time, the study on the thickness of shotcrete indicates the reasonable shotcrete thickness should considering both the rigidity and pliability properties. This study will be an important reference in designing the thickness of shotcrete in the anchoring reinforcement.

Key words: shotcrete, anchoring, reinforcement, reinforced earth retaining wall, numerical simulation
