摘　　要：冶勒水电站大坝属首座在400m级超深厚覆盖层上建成的坝高125m沥青混凝土心墙堆石坝,基础防渗最大深度达200m,工程勘察设计难度极大。本文主要就冶勒水电站坝基超深厚覆盖层的工程地质特性及主要工程地质问题有关研究成果进行了总结。Yelei Hydropower Station dam is the first bituminous concrete core rockfill dam with its height of 125m built on extra-thick（ about 400m）overburden. The largest depth of the dam foundation cutoff wall reaches 200m. Investigation and design of the project are extremely difficult. In this paper, the main study results of the engineering geology properties and major problems of Yelei Hydropower Station dam foundation extra -thick overburden are summed up.
