| Abstract: | 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. |
