As a critical safety structure in cemented paste backfill (CPB) systems, traditional reinforced-concrete barricades exhibit high load-bearing capacity but suffer from design limitations due to the neglect of slurry rheological properties and time-dependent characteristics, leading structural failures resource inefficiency. This study proposes lateral pressure theoretical model incorporating time dependence, grounded yield stress-resting evolution CPB. Results demonstrate that backfilling height predominantly governs pressure. A mechanical reinforcement was developed using plastic hinge line theory two-way slabs, deriving computational formulas for horizontal vertical quantities. Key findings indicate requirements are influenced by height, width-to-height ratio (W/H), rebar diameter, strength, while horizontal/vertical solely depends on W/H. strength fusion theory, integrating area ratios through limit state methodology, reveals composite is primarily determined tensile concrete unconfined compressive (UCS), ratio, with UCS being dominant factor. enables thickness determination based enhancing scientific rigor. The systematic framework sequentially calculates pressure, thickness, configuration. Case validations confirm 28%–35% reductions consumption 1–2 specification grade decrease diameters, field applications stable barricade performance during operations.
