Abstract:
The dam for the Laxiwa Hydropower Station is a double-curvature thin arch dam with the maximum dam height of 250m and is located in the cold highland area. The concrete of dam body adopted the pouring throughout working surface. To ensure the concrete quality and according to the characteristics of the Laxiwa Hydropower Project, we deter-mined that the technical requirements of raw materials of concrete and the design principle of concrete mix proportion and put forward the concrete mix proportion thatis suitable to this project.[著者文摘]
