Stability Calculation of High Side Slope of Diversion Power System Inlet on Left Bank of Jinchuan Power Station
The diversion power system intake excavation of Jinchuan Hydropower Station forms a slope of about 160m height; its stability is one of the main geological problems of the project. By detailed site investigation, the engineering geological characteristics of intake slope (including the lithology, slope structure, the structural surface and its combinations, rock weathering and unloading, hydrology etc) is analyzed in this paper. On the basis of site slope ratio statistics, the problem of how to select a safe and economic excavation slope ratio has been studied. The finite element method and rigid limit equilibrium method were used to calculate and analyze slope stability under various working conditions. The results of analysis evaluation provide a scientific basis for the design and construction.
