The underground Ust’-Khantaisk hydroelectric station
Conclusions Experience in construction and in the first period of operation of the Ust’-Khantaisk HES merits the following conclusions: 1. Passing discharges over a partially erected rock-fill dam in the construction of a hydrocenter is technically feasible, dependable, and economically advisable for rivers with a flow regime typical of northern regions. 2. An underground HES building is most suitable for northern hydroelectric stations. 3. Existing instructions on antiseepage arrangements in dams are very laborious. It is therefore necessary to seek new technical solutions. Use of polymer materials deserves special attention, but their durability must be thoroughly investigated. 4. The lack of an excavator with a 3–5-m3 bucket for work under northern conditions and of large capacity cranes must be pointed out. 5. The labor-consuming nature and difficulty of building dams on a soft foundation composed of lacustrine-swampy and lacustrine-glacial deposits in boggy, and permanently frozen states call for new technical solutions and for the design of special earth-moving equipment suitable for work under such conditions.
