坪溪水库坝体填土渗透稳定评价及处理建议

Pingxi Reservoir Dam Sappage Stability Evaluation and Treatment Suggestion

坪溪水库坝体为填土坝,坝基未处理,填土均放在强风化和全风化粗粒花岗岩上,填土以全风化和强风化花岗岩为主,局部夹有坡积土和砂岩全风化土,由碾压法和水坠法筑成,透水性不均匀且较大,本文通过分析填体填土的质量、渗透稳定性并提出处理建议。

The dam of Pingxi Reservoir is a rolled_earth filled dam. Its foundation is formed completely and highly by weathered coarse_grained granite without treatment. The earth_fill's quality and seepage stability are examined by engineering geological exploration. The result shows that the earth dam has a good engineering geological performance without seepage failure.
