Model Test of Anchoring Effect on Zonal Disintegration in Deep Surrounding Rock Masses
Figure 5
Sketch and photos of the true 3D model test system. The model was set inside the frame, and the platen was set into the frame at 0.5 cm depth. Then, each direction of the model has the reserved displacement of 9 cm. Notes: (1) junction plate, (2) hydraulic jacks, (3) loading platen, (4) oriented frame, and (5) combination reaction frame for loading (6) excavation guiding platen.
