摘要: 洛渡拱坝最大坝高285.5 m,蓄水之后,渗流广泛存在于坝体和坝基之中,可能会威胁大坝安全。为掌握大坝的渗流状态,根据溪洛渡水电站初蓄-运行期大坝渗流监测成果,分析和评价了渗流变化规律和分布特征,为评估大坝运行安全提供依据。结果表明:溪洛渡大坝防渗帷幕及排水幕效果良好,帷幕后及排水幕后渗压折减系数均在设计允许范围以内,绕坝渗流状态合理,渗流量趋于稳定,大坝在初蓄-运行期的渗流发展过程和分布特征符合一般的认识规律,状态正常。

Abstract: The maximum height of Xiluodu arch dam is 285.5 m. Seepage water is found in dam body and foundation after impoundment, which is a potential threat to dam safety. To get seepage behavior, seepage monitoring data is used to analyze variation and distribution rules of seepage. The results show that, anti-seepage curtain and drainage holes of Xiluodu dam have played their own role well; monitoring values of osmotic pressure are within allowable design range; the status of seepage around Xiluodu dam is reasonable and seepage flow tends to be stable.
