柳树沟水库大坝浸润线观测分析

Observation and analysis of main dam phreatic line for Liushugou Reservoir

介绍了新疆沙湾县柳树沟水库的工程概况,分析了大坝的工程地质条件。通过对大坝浸润线及坝基、坝肩绕渗的观测与分析,结果表明,水库拦水坝固结灌浆防渗效果良好,坝体及左右岸坝肩渗流场基本稳定,岩体内渗流水位偏高。为保证大坝运行的安全性,还应持续加强观测。

An introduction was made on the general information of Liushugou Reservoir located at Shawan County of Xinjiang.The engineering geological conditions of main dam were analyzed.The results of observation and analysis of the dam phreatic line,dam foundation and abutment seepage demonstrate the dam consolidation grouting renders good anti-seepage effects;the seepage field is basically stable at dam body as well as left and right abutments;the seepage level in rock mass is high;continuous observation shall be strengthened to ensure dam safety.
