Influence of structural surface roughness on the strength of layered fill bodies based on PFC2D

The stratified structure of underground backfill can reduce the overall physical performance, potentially causing safety issues during mining operations. To improve the bonding quality between layers, four molds with different roughness levels (R1, R2, R3, and R4) are prepared using 3D printing tech...
