乌江渡水电站绕坝渗流监测与分析

Monitoring and Analysis of Seepage Around Dam of Wujiangdu Hydropower Station

通过分析地下水位长期观测孔原布置存在的问题,提出并实施了对长期观测孔的自动化改造。通过分析对比人工观测和自动化监测数据,得出结论:人工观测数据质量较差,不能很好地反映两岸地下水位的情况;而自动化监测数据质量相对较好,多数能够反映两岸地下水位的变化规律。分析结果表明绕坝渗流和两岸灌浆帷幕运行情况良好。

By analyzing the problems existing in the original layout of the long-term observation holes of groundwater level,the automatic reformation of the long-term observation holes is proposed and implemented.By analyzing and comparing the data obtained from manual observation and automatic monitoring,it is concluded that the quality of manual observation data is poor,which can not well reflect the situation of groundwater level on both sides;while the quality of automatic monitoring data is relatively good,most of which can reflect the change rules of groundwater level on both sides.The results show that the seepage around the dam and the grouting curtain on both sides are in good condition.
