摘要
自1989年岩滩碾压混凝土围堰在施工中创造性的使用变态混凝土以来,变态混凝土技术发展迅速且施工工艺日臻完善。本文以江垭工程为例,对变态混凝土的配合比设计、施工工艺、质量保证措施以及变态混凝土的优缺点进行了介绍。
The technology of enriched vibrated RCC (EVR) has had a fast development since its first creative application in the cofferdam construction for Yantan hydropower station in 1989, and its construction process is becoming perfect. An introduction is made to the mix proportion design, construction process, quality control measures and the advantages and disadvantages of the EVR, taking Jiangya project as an actual example.
