| 中文摘要: |
| 本文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。 |
| 英文摘要: |
| The surface crack investigation and no damage detection have been researched into new pouring concrete on the overflow dam. The stress distributing problem has been simulated with finite element method. Based on investigation in situ, no damage detection and theoretical analysis, the reason of cracking has been totally studied. This will provide reference values for looking for crack strengthening method and dam strengthening plan in the cool regions. |
