何庄水库除险加固渗流效果分析

针对何庄水库目前的病害特点,结合坝身、坝基土层的工程地质特征,对主坝坝身、坝基采取灌浆防渗处理。在大坝上游迎水面兴利水位以上采用浆砌块石护坡,兴利水位以下采用C15混凝土护面。在坝后渗水段增设坝后贴坡排水。通过防渗处理后大坝的渗流性态得到了较大的改善。

Seepage Analysis of Danger Control and Reinforcement of Hezhuang Reservoir

According to the current disease characteristics of Hezhueng Reservoir, end in combination with the features of engineering geology of dam body end foundation, treatment of grouting in dam body end foundation for enti-seepage was applied. Stone pitching was adopted above the profitable water level on upstream face, end C 15 concrete face was adopted under the profitable water level. Drainage embankment slope was set up on the downstream face, water seeping away. Through enti-seepage treatment, anti-seepage behavior of dam has been greatly improved.
