水库黏土斜墙坝渗流分析及解决方案

Analysis on reservoir clay inclined wall dam seepage and solutions

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。

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 4working 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.
