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

深厚覆盖层具有透水性强、抗冲能力差的特点，极易发生渗透变形或渗透破坏，直接影响到上部建筑物的安全。（剩余1994字）
