Characteristics of Rock Slope Excavation Deformation and Failure and Analysis on Cable Bolting |
| |
| Abstract: | Based on a large-scale excavation slope in Bijie, Guizhou province, High-density electrical method, statistics of rock structural surface and geological investigation method were used to obtain the slope structural characteristics. The rock slope excavation deformation and failure characteristics were revealed through site investigation, monitoring and finite element simulation analysis and the sliding-tension deformation and failure model of the slope was obtained. The cable bolting program was put forward and the effect was analyzed via numerical simulation. |
