摘要
小浪底水利枢纽工程大坝防渗体系由施工围堰前天然铺盖、围堰防渗墙、围堰斜墙、内铺盖、大坝斜心墙及大坝处防渗墙、灌浆帷幕等构成,基于10余年渗流监测数据,对比分析了铺盖、大坝防渗墙及灌浆帷幕的渗透性能,评估了铺盖、大坝防渗墙及灌浆帷幕的防渗效果,结果表明在目前运行条件下大坝防渗效果显著。
The dam seepage prevention system of Xiaolangdi hydropower project is composed of natural blanket, cofferdam cut-off wall, cofferdam inclined wall, inner blanket, inclined core wall, dam cutoff wall and grouting curtain. Based on more than 10-years seepage monitoring data, the seepage properties of blanket, dam cutoff wall and grouting curtain are comparative analysis. At the same time, the seepage prevention effects of blanket, dam cutoff wall and grou ting curtain are assessed. The results show that the seepage prevention effect of the dana is remarkable under the current operation conditions.
