摘要
大坝渗流基流是反映大坝渗流性态的重要指标之一 ,文章结合南水大坝渗流实测资料 ,采用多种模型和方法对大坝的渗流基流进行了分析 ,并根据模型分离结果推求了坝体、坝基和两岸绕坝渗漏基流下包线的表达式 ,进而分析和评价南水大坝的渗流状态。
Seepage base flow is an important index to reflect the behaviour of seepage flow in a dam. The behaviour of seepage flow is analyzed by use of various models and methods together with observation data, and expressions of the lower boundary line for the base flow in the dam body, the dam foundation and side banks are derived from the model results, and the behaviour of seepage flow is analyzed and appraised for the Nanshui dam.
