摘要: 桃源水电站土石副坝为碾压土石坝,坝体填筑料主要为天然砂砾料,级配不良,采用高喷灌浆防渗墙防渗。水库建成蓄水后,土石副坝下游坝脚与混凝土闸坝结合部位附近出现渗漏点。通过分析土石副坝渗透破坏的形式,结合监测结果,分析坝体渗流稳定性。

Abstract: The auxiliary dam of Taoyuan hydropower station is a compacted earth rockfill dam. The main filling material is natural gravel with poor grading. High pressure grouting wall is adopted as seepage cut-off wall. After impoundment, seepage is found at the connection area of dam foot and concrete gate dam. Combined with seepage monitoring data, by analysis of seepage failure modes, the seepage stability of dam is studied.

Key words: earth rockfill dam, seepage, seepage stability
