Feasibility study on construction of RCC gravity dam under special climatic conditions in Tibet

According to the experience in construction of water conservancy and hydropower projects Mainland, RCC dam has two main advantages: rapid speed roller compacted concrete can realize early power generation, price fly ash is much lower than that cement, which reduce project cost. Tibet special geographical environment climatic conditions, generally characteristics “high altitude, low pressure, temperature, large temperature difference between day night, dry climate”. Taking dam-building central as an example, through investigation research analogy similar projects, this paper analyzes adaptability gravity dams from aspects environment, material properties, progress, Adaptability high altitudes. It provides a reference for choosing safe, reliable, economical reasonable type projects. selecting types engineering construction.
