| Abstract: | SummaryThe Elasto-Visco-Plastic Analysis for Rock Displacement of the Foundation Pit of a Water Power Plant In this paper a method used in the elasto-visco-plastic analysis is proposed. It has been employed for deformation analysis of the foundation pit of a large water power plant in China.The back analysis of this rock engineering problem shows that the relief of the rock initial stresses due to excavation and the rheological properties of the weak intercalations and the rock masses as well are the main factors which caused the large deformation of the foundation pit.The results from the calculations are coincided fairly well with the data measured and observed in situ.With 16 Figures |
