Abstract: In construction of RCC dams in Xinjiang, several climate factors must be considered, such as dry air, frequent alternation of dryness and humidity, larger temperature difference between day and night, and severe freezing and thawing cycles within a year. A series of studies have been conducted to apply new technologies, new materials and new processes to RCC dam construction in extreme cold regions with higher latitude and worse climatic conditions in order to overcome the problems caused by the climate factors above. Until now, four RCC gravity dams and one RCC arch dam have been completed in Xinjiang. This paper presents a summary of the achievements in theoretical research and technological renovation aimed at dam construction in Xinjiang and other extreme cold regions, focusing on concrete materials, construction technologies, and temperature control measures. In addition, we discuss the existing difficulties and relevant technological issues, providing lessons and suggestions for further development of the technologies for other similar regions.
