Abstract: The impervious measures of deep overburden directly affect the normal water storage of Sluice dam and the seepage stability of gate foundation. In this paper, the seepage stability and dam settlement of deep overburden of gate foundation of LalaShan hydropower station are analyzed by finite element analysis and theoretical calculation method, and the corresponding anti-seepage treatment measures are put forward, the research results have reference value for similar projects.
Keywords: sluice dam; deep overburden; seepage; foundation treatment
