| Abstract: | According to the landform, geological and hydro-geologic conditions of thin mountain ridge at left dam abutment of the Yangqu Hydropower Station, this paper analyzes the seepage path and leakage possibility of reservoir water through the Quaternary formation developed at the old channel of saddle back. By establishing the three-dimensional numerical calculation model, the seepage path and leakage amount of reservoir water through the thin mountain ridge is evaluated and the parameter sensitivity analysis is carried out. And then the problem of seepage stability of Quaternary unconsolidated formation of downstream bank slope of saddle back was appraised. |
| Keywords: | leakage amount seepage deformation thin mountain ridge hydro-geologic model Yangqu Hydropower Station |
