| Abstract: | In this paper, the authors carried out a numerical simulation towards deformation along with the excavation using FLAC^3D. We obtained the rule of the displacement distribution under the condition of excavation and soil nail supporting, at the same time we put forward the best time of the soil nail supporting according to the change of the maximal unbalanced force. |
