In many large shotcrete anchor support works, shotcrete layer reinforced by wire mesh is one of the important structures to guarantee stability of works, but in the former researches, analysis about this is comparatively less. In the light of reduplicative tests on the support of practical works, this paper establishes the deflection function which fits for stress deformation of shotcrete layer, and deduces the stress distribution rule in the shotcrete layer. Finally, on the basis of the practical reinforcement of the retaining wall, it is verified that the new support method of shot concrete with local two layers of steel bar nets can gain good effect of support.
