水库黏土斜墙坝渗流分析及解决方案

本文以抚顺太平沟水库为研究对象,对其黏土斜墙坝的渗流问题进行分析。分析过程中,运用Autobank软件对4种工况下黏土斜墙坝渗流进行模拟。结果表明:工况1下,黏土斜墙坝坝体、坝基渗透较为严重,黏土斜墙变形、坍塌可能性较大;工况4下发生渗透变形的风险很低。在正常蓄水情况下,设置防渗墙和土工膜具有相对理想的防渗效果。

Analysis on reservoir clay inclined wall dam seepage and solutions

Fushun Taipinggou Reservoir is regarded as a research object for analyzing clay inclined wall dam seepage problem.In the analysis process,Autobank software is applied for simulating clay inclined wall dam seepage under 4 working conditions.The results show that clay inclined wall dam body and foundation suffer from more severe seepage under working condition 1 ,and the clay inclined wall deformation and collapse possibility is higher.The seepage deformation risk is low under working condition 4.The setup of cut-off wall and geomembrane has relatively ideal anti-seepage effect under the condition of normal water storage.
