摘　　要：石门拱坝坝基渗流性态及其主要影响因素在两个不同的防渗区域存在显著差异 ,通过对渗流、坝踵裂缝等观测资料的综合分析 ,揭示了不同防渗措施对坝基渗流影响的机理 ,对石门拱坝坝基渗流安全性进行了评价 。There is obvious difference in the foundation seepage property and its main affecting factors between the two zones of Shimen arch dam. The article reveals the mechanism of effect of different seepage prevention methods on Shimen arch dam foundation seepage property, evaluates its safety by synthetic analysis of seepage and dam heel crack observation data, and discusses some engineering measures to improve the foundation seepage conditions.
