In the paper,full length adhesive anchor cable reinforcement surrounding rock is adopted as an example,finite element software FLAC3D is utilized for modeling aiming at superiority design issue of pre-stressed anchor cable reinforcement surrounding rock in underground cavern project.Anchor shear resistance performance simulation study and theoretical discussion are implemented. Calculation results of before and after adhesive pre-stressed anchor cable reinforcement under the two plans are compared. Surrounding rock adhesive pre-stressed anchor cable supporting mechanism of underground cavern project is described.Superiority of adopting adhesive pre-stressed anchor cable reinforcement surrounding rock is explained.The paper can provide certain reference for project designers.
