摘要
根据羊曲水电站左坝肩单薄山梁的地形地质条件及水文地质条件,分析了蓄水后库水通过垭口古河道内第四系地层渗漏的可能性及渗漏途径。通过建立三维数值计算模型,分析了库水通过单薄山梁的渗流途径及渗漏量,并进行了参数的敏感性分析。在此基础上,评价了垭口处下游岸坡第四系松散层的渗透稳定问题。
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 threedimensional 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.
