根据肖克尔水库的实际情况，通过渗流有限元计算分析，全面评价了水库大坝的渗流状况。结果表明：大坝坝基由低液限粉土、粉土质砂组成，坝基渗透较严重；坝基清除不彻底，坝体与坝基间接触渗漏；在水库正常蓄水位时，0＋100坝段、0＋600坝段下游坝坡出逸段及下游坝基水力坡降大于允许坡降，坝体坝基有发生渗透破坏的可能。大坝渗流安全评价为C级，建议采取相应加固处理措施，并完善渗流监测设施。
根據肖剋爾水庫的實際情況，通過滲流有限元計算分析，全麵評價瞭水庫大壩的滲流狀況。結果錶明：大壩壩基由低液限粉土、粉土質砂組成，壩基滲透較嚴重；壩基清除不徹底，壩體與壩基間接觸滲漏；在水庫正常蓄水位時，0＋100壩段、0＋600壩段下遊壩坡齣逸段及下遊壩基水力坡降大于允許坡降，壩體壩基有髮生滲透破壞的可能。大壩滲流安全評價為C級，建議採取相應加固處理措施，併完善滲流鑑測設施。

A comprehensive evaluation is carried out on the seepage safety of Xiaokeer Dam using the finite element seepage analysis.Results show that the seepage through the dam foundation is rather serious, as the foundation is mainly consisted of low liquid limit silt and silty sand.Leakage may occur in the contact between the dam and the foundation due to incomplete clearing of the dam foundation.When the reservoir is in its normal water level, the hydraulic exit gra-dients of the downstream dam surface and the foundation in 0+100 and 0+600 dam sections are greater than the per-missive gradient, which means the seepage failure may occur in these locations.Overall seepage safety of the dam is de-fined as level C.Necessary reinforcement measures are recommended and seepage monitoring devices should be im-proved.
