油啥水库下闸蓄水前渗漏风险分析OA
Risk Analysis of Yousha Reservoir Seepage before Gate Closure and Water Storage
水库安全和可持续运营直接关系到周边地区的经济效益.本研究采用压水试验和有限元分析法,分别对坝基渗透性和坝坡渗流稳定性进行分析.结果表明,共计完成压水试验81段,其中水平趾板J-2号孔第2段基岩段的透水率最高,透水率为2.91 Lu,符合防渗标准3 Lu的要求;采用AutoBank有限元模拟软件进行了5种可能工况的坝坡稳定性计算,各工况下的安全系数均满足规范要求.由此认为,水库在渗流作用下坝基和坝坡基本稳定,无渗漏风险.
The safety and sustainable operation of the reservoir is of great significance to the economic benefits of the surrounding areas.The study employs piezometric tests and finite element analysis methods to evaluate the seepage stability of the dam foundation and dam slopes,respectively.The results show that a total of 81 sections were inspected in the piezometric tests,with the highest permeability rate found in the horizontal toe plate hole J-2,section 2 of the bedrock,which was 2.91 Lu,meeting the anti-seepage standard of 3 Lu.The AutoBank finite element simulation software was used to calculate the dam slope stability under five possible conditions,and the safety factors under each condition met the regulatory requirements.It is concluded that under the action of seepage,the dam foundation and slopes are basically stable,and there is no risk of reservoir leakage.
