【摘要】 为了解某水库大坝的渗流状况以防止发生渗透破坏,采用定性与定量分析的方法对某混凝土面板堆石坝坝基的F4断层、防渗帷幕和坝体坝基等渗流监测资料进行了详细地分析,并建立了渗流监测资料的多因子回归统计模型。分析成果表明:F4断层帷幕和趾板帷幕灌浆防渗效果良好,大坝渗流符合一般的渗流变化规律。大坝渗压水位的多因子回归统计模型拟合效果较好,大坝渗流与库水位及降雨呈正相关关系,与时效因子关系较小。运行了近10年的某面板堆石坝的渗流状况目前处于正常状态,为确保大坝安全运行,建议加强对监测仪器的维护,充分发挥监测的作用。更多还原

【Abstract】 In order to understand the seepage condition of a reservoir dam and prevent seepage failure.The method of qualitative and quantitative analysis is adopted to analyze the seepage monitoring data of the F4 fault,the impervious curtain and the dam foundation of a concrete faced rockfill dam foundation.And a multi factor regression statistical model for seepage monitoring is developed.The results show that the curtain anti-seepage effect of F4 fault and plinth are good.And the seepage of dam is consistent with the general law of seepage change.The multi factor regression statistical model of dam seepage water level has better fitting effect.And the seepage of dam is positively correlated with reservoir water level and rainfall,and has little relationship with aging.The seepage of a face rockfill dam which has been running for nearly10 years is in normal condition.It is suggested to strengthen the maintenance of monitoring equipment,and ensure the safe operation of the dam.更多还原
