Summary: | The Far North of Russia has a strong power generation potential. Future hydraulic power engineering projects may include construction of major power generating plants in south Yakutia. The core elements of the proposed projects will comprise dams about200 meters high.The authors substantiate construction of a masonry dam in severe climatic conditions of the Far Northern region of Russia. The structural solution represents a masonry dam having an impervious element, or a wide internal membrane, made of soil and cement concrete. This element is to protect the soil-free membrane from any thermal effects. The authors provide their analysis of the deflected mode of the dam, if its height is equal to 226 m. The findings have proven that the membrane made of soil and concrete cement will be in the state of compression. Therefore, the authors believe that the proposed design of the dam structure is reliable enough. Обосновано применение в суровых климатических условиях Крайнего Севера России каменной плотины с противофильтрационным элементом в виде внутреннего широкого экрана из грунтоцементобетона. Это позволит защитить негрунтовый экран от температурных воздействий. Приведены результаты расчета напряженно-деформированного состояния плотины такой конструкции высотой 226 м. Они показали, что грунтоцементобетонный экран будет находиться в сжатом состоянии. Это позволяет говорить о надежности плотины такой конструкции. |
