摘要
经20多年的试验研究和工程实践,我国碾压混凝土筑坝技术在混凝土配合比、大坝填筑的入仓方法、摊铺与碾压、模板工艺、坝体分缝以及坝体防渗、温控防裂等方面取得了一批有价值的成果,推动了我国碾压混凝土筑坝技术的快速发展,已建、在建碾压混凝土大坝84座,多项指标为国际领先水平。
With more than twenty years' experiment, research and construction practice, a lot of valuable achievements have been obtained in the fields of both design and construction technique concerning RCC dam technique, such as, concrete mixing ratio, work method of concrete filling of dam, paving and rolled compact, formwork, jointing of dam as well as seepage-proof treatment of dam, temperature control and cracks prevention etc., significantly promoting the rapid development of RCC dam technique in China. There are 84 on-going or completed RCC dams, many indexes ranking head in the world.
