摘　　要：对九甸峡水利枢纽工程深厚覆盖层的勘察研究,查明了深厚覆盖层地质结构和工程特性,科学合理地确定了建基面,推荐了合理的坝型——面板堆石坝。充分利用密实可靠的覆盖层作为坝基,有效避免了因深开挖带来的诸多问题,极大地提高了经济效益。The geological structure and engineering characteristics of the deep overburden for Jiudianxia Hydropower Project dam site were identified and the dam base surface was scientifically selected after detail investigation and research.The concrete face rockfill dam was proposed.By using compact overburden as dam foundation,the problems caused by deep excavation will be avoided and the economic benefits can be improved.
