| 中文摘要 | 针对高纬度严寒寒冷地区特有的气候干燥、干湿交替频繁、昼夜和年际温差大、冻融循环剧烈等恶劣的气候条件,新疆碾压混凝土坝建设在新技术、新材料、新工艺等方面开展了一系列的研究工作,先后建成4座碾压混凝土重力坝和1座碾压混凝土拱坝。本文从混凝土材料、施工工艺、温控措施等方面,总结了新疆等严寒寒冷地区碾压混凝土坝建设所取得的理论研究和技术创新成果,并对存在的难点及相关技术问题进行了分析探讨,为严寒、干旱地区同类坝型筑坝技术发展提供借鉴。 |
| 英文摘要 | 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. |
