| Abstract: | In this paper the powerhouse chamber complex of Xiluodu Hydropower Station is investigated in detail using random joint distribution model and non-linear elestic-plastic finite element method.The deformation,stress field and disturbed zones of the surrounding rock mass are studied and differences between the chamber complex with and without support are analysed emphatically.Moreover regions and failure forms of potential unstable rock blocks are found out.Influence of exposed shear zone position on the main powerhouse crown is discussed.The study results offer a useful reference to optimization design of the support in the future. |
