With the development of economy, the adjustment of industrial structure, the improvement of people's living standard and the expansion of urbanization, the structure of the city has changed a lot. The proportion of industrial use of electricity decreased year by year, the proportion of household electricity, commercial electricity and public utilities increased year by year, the peak and valley change increased year by year. Therefore, the construction of hydropower project, to improve the current situation of the system of regulating the power grid, has a positive role in promoting. Reinforced rock fill dam with face slab in foreign countries has been built and at the dam more than 50m high dam more than 70 seats, of which more than 100m high dam 18. At present, Brazil estuary aliya rock fill dam is the highest dam in this kind of dam in the world, built in 1980, has been running well. Our reinforced rock fill dam with face slab design and construction technology in the introduction of digestion and absorption of foreign advanced experience in the foundation, the systemic research on a considerable scale. The design level and construction technology of the rock fill dam with face slab in our country have reached the international advanced level by the complete technology of the construction of the 100m level rock fill dam with face slab. This paper mainly from the rock fill dam with face slab, dam type selection and layout of water conservancy project comparison; dam profile design; detail dam; dam high determined; stability analysis; strength calculation; overflow capacity check aspects were studied. 展开更多
