摘要
渗流监测数据是判断堰塞体稳定性的重要依据。通过实时监测并分析渗流监测数据,了解坝体内部的渗透压力,从而评价防渗墙的防渗效果,有助于及时发现并处理坝体内部的渗漏问题,防止因渗漏导致坝体失稳或溃坝等严重后果。本研究采用红石岩堰塞体渗流监测资料,从堰塞体渗压水位、浸润线、渗流稳定性等方面分析了堰塞体渗流变化及防渗效果。结果表明,堰塞体渗压水位与库水位相关关系稳定,大坝未见渗透变形情况,说明红石岩堰塞体采取的防渗墙+帷幕灌浆的渗控体系可以很好地满足堰塞坝防渗要求,堰塞体工程整体运行安全。
The seepage monitoring data is an important basis for judging the stability of landslide dam.By real-time monitoring and analyzing the seepage monitoring data,the seepage pressure of dam body can be understand,thereby the effect of anti-seepage wall can be evaluated,which helps to timely discover and deal with the leakage problem of dam body,and prevent serious consequences such as dam instability or dam failure caused by leakage.Based on the seepage monitoring data of Hongshiyan landslide dam,this paper analyzes the seepage changes and anti-seepage effect of the landslide dam from the aspects of seepage water level,infiltration line and seepage stability.The results show that the correlation between seepage water level and reservoir water level is stable,and no seepage deformation is observed in the dam.Therefore,the seepage control system of anti-seepage wall and grouting curtain adopted by Hongshiyan landslide dam can well meet the anti-seepage requirements,and the dam project operates safely.
