- •
An optimized DDARF is proposed to simulate failure process and anchorage effect of jointed rock mass.
- •
This numerical method is verified through an experimental similarity test.
- •
The one-joint specimen with one rock bolt under 11 schemes are simulated and the optimal reinforcing position is obtained.
- •
The one-joint specimen with 2 rock bolts under 3 schemes are also simulated.
- •
To effectively restrain crack propagation using rock bolt will improve surrounding rock mass stability.
