Abstract
The dam of Jinghong Hydropower Project, a RCC gravity one at full section, is located in the lower and hot valley of the Lang-cangjiang river catchment where the temperature is high and it rains often.The construction period at high temperature each year lasts 7~8 months.Therefore, the temperature of the dam concrete is strictly required to control.Measures for the temperature control are com-plicated.Meanwhile, the project work is in a large quantity and the construction strength is high.Construction of normal concrete, RCC and installation of penstocks in the dam are interfered largely.So, the construction difficulties are so high.In the paper, scheme for dam concrete construction, raw materials, concrete mix ratio, temperature control measures, new materials and new technology are totally in-troduced in combination of the site construction practice of Jinghong Hydropower Project.The project construction speed is called Jinghong Speed and the project is awarded the First Prize-winning one of Yunnan Province.关键词
