摘要
Abstract
The area of bedding concrete for the core-wall in Nuozhadu Dam is large with a thin thickness, and then is a kind of thin-wall concrete; for which the for mwork erection and concrete placement are difficult due to few passages in the construction site and more steep slopes on both the banks of the core-wall, furthermore, the anti-cracking of the concrete is quite difficult as the weather therein is quite torrid with a large temperature difference between day and night. The causations of the cracking of the bedding concrete and the anti-cracking technology for the construction are analyzed and studied herein through the construction practice concerned.关键词
