摘要
水利工程建设中,为了避免因围堰失事而造成毁灭性的破坏,需要对围堰的防渗、稳定等问题予以更多的重视。通过对大渡河深溪沟水电站上游围堰三维渗流稳定计算结果进行分析,比较了悬挂式防渗墙与全封闭防渗墙的差别,验证了土工膜和混凝土防渗墙的复合防渗体系的设计方案的合理性。
Under the construction of hydraulic engineering,we should take the prevention of cofferdam seepage and the stability more seriously in order to avoid cofferdam crash and inflicting devastating damage.Through the calculation results analysis of the 3D seepage stability of the upstream cofferdams of Shenxigou Hydropower Station,we compare the difference between the suspended type of impervious walls and the total enclosed type.And the rationality of the design proposal for the geomembrane and concrete cut-off walls in the compound impervious system is verified.
