摘　　要：国外采用全库盆土工膜防渗的土坝较多,现行国内外规范缺少针对单项工程的土工膜锚固方法的具体指导与相关锚固指标。针对均质土坝,国内通常采用坝顶槽型锚固沟锚固同时表面压覆,欧洲近年来开始采用坡面纵向锚固槽锚固。总结了坝顶槽型锚固沟与坡面纵向锚固槽的锚固形式与计算方法,提出了均质土坝如何选用锚固方法的建议,同时给出相关参数取值参考。There are many earth dams used in the whole reservoir basin abroad for seepage prevention by geomembrane. Current domestic and international codes lack specific guidance and relevant anchoring indexes for the anchoring method of geomembrane for single project. For homogeneous earth dams, groove anchorage groove anchorage on dam crest is usually used in China while surface covering is carried out. Longitudinal slope anchorage groove anchorage has been adopted in Europe in recent years. The anchorage forms and calculation methods of groove-type anchorage ditch on dam crest and longitudinal anchorage ditch on slope surface are summarized. Suggestions on how to select anchorage method for homogeneous earth dam are put forward, and relevant parameters are given as reference.
