17th International Symposium on IceSaint Petersburg, Russia, 21-25 June 2004International Association of Hydraulic Engineering and ResearchRESEARCH OF ICE CONDITIONS FOR THE STRUCTURESOF TUGUR TIDE POWER STATIONS.I. Kovalevskij 1 , L.M. Monosov 2 , A.M. Tsibin 1ABSTRACTFor work of hydrotechnical structures in difficulties ice condition is required the developmentof actions for maintenance of its careful exploitation. The results of nature researchhad permitted to begin the development of actions for protection from ice influencein bases structures of Tugur tide power station.The energy of tide power stations is essential alternative for thermal and atom powerstations. There are on in Russia many regions with high value of tide. Particularly, Kolapeninsula – the value of tide is about 4 m, Lumbov Gulf - about 7 m, Mezen Gulf -about 9 m. The essentials values of tide are observed in Okhotsk sea, for example, inPenzhin Bay - about 13 m, in Tugur Gulf - about 9 m. In the regions of these water areasare difficulties ice and climatic conditions that are considered by designation, constructionand exploitation of tide power stations.The above mentioned Tugur Gulf lies in west part of Okhotsk sea.The length of lied from north to south Tugur Gulf is 74 km and the width is about37 km. The Shantar islands from north side are natural protections by influence of ices(The tides power stations, 1994).The length of dam of tide power station with the building of station lied inside of it willbe 18 km. The water will be passed as well across water aggregates as across culvertholes.For careful exploitation of aggregates including in period of Freeze-up must be developedrespective actions.For reception of dates about ice conditions in Tugur Gulf by small level of scrutiny forthis question (Monosov and other, 1991) was necessary the carrying out of ice-researchworks in Tugur Gulf. Particularly, the air and ice investigations bas carried out, includingice-mesure survey and determination of ice and water salinity.Resulting of investigations are received the dates, permitting to determine the basescharacteristics of ice regime of Tugur Gulf in natural conditions.1 All – Russian Jnstitute of Hydraulic Engineering (VNIIG), Gzhatskaya str., 21, St.Petersburg, Russia2 Plant Everest367
