丰满大坝是国内建坝最早、问题最多、病害最严重的大型水工建筑物 ,经论证 ,决定将预应力锚固作为大坝加固处理的主要措施之一 .1988～ 1997年实施此项加固工程 ,在坝顶、溢流堰、基础检查廊道内共布置了 870～ 6 0 0 0 k N七种不同荷载级别锚索 381根 .对锚固工程施工质量和锚固效果进行分析和评价 ,其结论是 :施工工艺流程严格 ,原始资料详细齐全 ,施工质量良好
Fengman dam is the earliest construction dam in China, the most problematic, the most serious disease of large hydraulic structures, the demonstration, decided to prestress anchorage as one of the main measures to strengthen the dam .1988 to 1997 implementation of the reinforcement project , A total of 381 anchor cables with 770 ~ 60 000 k N load levels were arranged on the crest, overflow weir and basic inspection corridor. The construction quality and anchoring effect of anchorage engineering were analyzed and evaluated, and the conclusion was that : Strict construction process, complete the original data, construction quality is good
