布拉茨克水电站的混凝土坝是俄国首座高度超过 10 0m的混凝土坝 ,其技术设计于 195 7年完成 ,195 8年夏季浇筑了第一块坝体混凝土 ,196 1年水库开始蓄水 ,196 7年 9月上游水位达到正常蓄水位。该混凝土坝是第一座建在多年平均气温为负温地区的、高度超过 6 0m的大坝 ,也是第一座在严寒气候条件下修建的体积超过 40 0万m3 的混凝土高坝。在俄罗斯的坝工建设实践中 ,这是第一次采用柱状分块浇筑 (不设接缝 ) ,并规定了一系列温度控制措施 :分区浇筑混凝土 ;用加碎冰拌和的方式预冷混凝土拌合物 ;用水管冷却已浇筑的混凝土。研究在运行过程中产生的主要问题及其产生的原因 ,处理经验以及保障混凝土坝 -基础系统今后安全可靠工作的基本方向
The concrete dam in Bratsk was the first concrete dam in Russia with a height of more than 100m. Its technical design was completed in 1957. The first dam concrete was poured in the summer of 1958, and the reservoir was started in 196-196 In September 2007, the upstream water level reached the normal water level. The concrete dam is the first dam built at a negative temperature in many years and with a height of more than 60 m. It is also the first concrete dam with a volume of more than 4 million cubic meters constructed under severe climatic conditions. In the practice of dam construction in Russia, it is the first time to use columnar block pouring (without seams), and a series of temperature control measures are provided: sub-district pouring of concrete; pre-cooling concrete mixing Compound; pipe with water cooling poured concrete. To study the main problems arising during the operation and their causes, to deal with the experience and the basic direction to ensure the safe and reliable work of the concrete dam-based system in the future
