| Abstract: | For the high slope of intake of diversion tunnel of Zipingpu Irrigation Project,the relationships of stress and strain are calculated by traditional mechanical methods of unloading and loading. The results on slope displacement calculated by the two methods of loading and unloading are compared,and the excavation unloading-induced deformation and corresponding support for the slope are shown in this paper. |
| Keywords: | rock mechanics slope unloading deformation reinforcement |
