果多水电站工程区海拔达3 400 m左右,多年平均气温5.6℃,昼夜温差大,外来物资运输条件差;受工程区特殊的自然气候及地理环境条件影响,与内地水电工程相比,独具特色。笔者全面介绍了在上述特殊地理和气象条件下开展勘测设计工作的方式和方法,碾压混凝土筑坝技术,施工组织设计,机电及金属结构设计,在工程施工过程中动态设计、持续优化,充分考虑工程的经济性和施工的便利等。
The construction area of Guo Duo Hydropower Station is about 3 400 m above sea level with an annual average temperature of 5.6 ℃. The temperature difference between day and night is large and the transportation conditions of foreign materials are poor. Due to the special natural climate and geographical environment in the project area, Features. The author comprehensively introduced the ways and methods of carrying out survey and design work in the above special geographical and meteorological conditions, the RCC dam construction technology, construction organization design, mechanical and electrical and metal structure design, dynamic design during construction, continuous optimization and sufficient Consider the economy of the project and the convenience of construction.
