Abstract：Traditional slope reinforcement measures adopt slope surface reinforcement such as anti-slidfing piles and cables，in which the depth from the surface to the inside of the slope is less than 80 m. While treatment measures aiming at large-scale potential sliding body with deep weak slip surface are not widely accepted yet，and the passive measures like avoidance and unloading are often employed. Taking the left high slope of Jinping I hydropower station as a case，the reinforcement principle and working conditions of deep embedded concrete shear resistance structures used for treatment of large engineering slope are analyzed；and the design methods of the shear resistance structures，including arrangement of tunnels trend，selection of cross-section types of tunnels，excavation ways and construction procedures，layouts for consolidation grouting holes around the tunnels and segmental and dislocation lamination pouring of backfill concrete，are systematically presented. Three-dimensional numerical results and field practice indicate that the proposed design method for embedded concrete shear resistance structures with the effects of replacement，adding strength and shear resistance for reinforcement of the rock slope with deep slip surface is valid. The proposed design method is not only helpful to ensure the safety of the left high slope，but also provides valuable experiences for the reinforcement of the high slopes of similar projects.
