摘　　要： 结合小川水库大坝现场检查及地质勘探情况,通过渗流观测资料分析坝体渗漏成因,得到排水廊道的设置对绕坝渗漏起到了改善作用。通过Auto Bank软件建立平面典型断面有限元模型,渗流参数计算得到浸润线规律符合均质坝分布;综合判断下游坝坡高水位工况下渗透稳定不满足要求。 This paper combined with the on-site inspection of Xiaochuan reservoir dam and geological exploration, through the analysis of the seepage observation data of dam, the leakage causes are analyzed, the conclusion found that the setting of drainage gallery can improve the leakage around the dam. The finite element model of plane section is established by Auto Bank software, and the seepage coefficient is calculated by parameter inversion analysis of seepage parameters. The seepage stability cannot meet the requirements under the condition of high water level of downstream dam slope.
