| Abstract: |
| Based on the engineering geological condition of one large-scale open-pit slope, firstly, the representative region was selected by rock quality evaluation and rock mechanics parameter analysis. Then, this paper employed FLAC3D to build the numerical model of large-size open-pit slope. Furthermore, with it to perform three-dimensional numerical simulation, revealing the mechanical environment of the oversized open-pit slope, exploring the final movement and deformation, stress distribution, and failure mechanism of the surrounding rock, and analyzing the final stress state, displacement, and plastic zone. Finally, all of these factors were respectively performed numerical simulation and analysis, which had crucial guiding significance of the design, optimization, and construction for this open-pit mine. |
