对丰满大坝溢流面新浇混凝土裂缝进行了表面调查、无损性态检测 ,采用有限元法模拟浇筑过程的应力分布 .在现场调查、检测和理论研究相结合的基础上 ,对裂缝成因进行了较全面的分析 ,这将对寻求裂缝补强方法和东北寒冷地区大坝补强加固可行方案的提出具有参考价值
The surface of newly-poured concrete cracks in the overflow area of Fengman Dam was investigated and the non-destructive behavior was tested, and the stress distribution in pouring process was simulated by finite element method.On the basis of field investigation, testing and theoretical research, A more comprehensive analysis, which will have the reference value for seeking the solution of the crack reinforcement and the feasible scheme of the dam reinforcement and reinforcement in the cold area in northeast China
