摘要
长河坝水电站大坝是建在深厚覆盖层上的高土石坝,大坝基础的防渗效果反映基础覆盖层的渗流状况,为防止大坝基础出现渗透破坏,故要准确监控大坝基础渗流渗压,正确判断基础防渗墙的运行状态。介绍了长河坝水电站大坝基础渗流监测中渗压计的布置情况,对大坝基础渗流情况进行分析评价。
As the dam of Changheba Hydropower Station is a high earth-rock dam which is built on deep overburden layer, the anti-seepage effect in dam foundation will reflect the seepage condition of foundation layer. In order to prevent seepage failure in dam foundation, it is needed to monitor the seepage and seepage pressure of dam foundation accurately, and to judge the operation state of foundation cutoff wall correctly. The layout of osmotic pressure gauge of seepage monitoring in dam foundation of Changheba Hydropower Station is introduced, the seepage in dam foundation is also analyzed and evaluated.
