| 摘 要： | 土坝应力——应变关系具有明显的非线性特征．采用了非线性有限元法对七一水库土坝进行变形和应力分析，全面了解坝体自施工以来的变形和应力变化规律、计算结果符合现状，并由此采取相应坝体加固措施，改善坝体的应力状态，可以解决坝体变形问题，达到除险加固的目的．

| Abstract: | The characteristics of the relationship of the stress-strain of earth dams is obviously non-linear.The stress-deformati0n of the core-wall earth dam of Qiyi Reservoir is analyzed by the non-linear finite element method in order to know the deformation and stress law o f the dam of Qiyi Reservoir body since it was constructed.The calculation results is cooresponding with its present situation.The relevent measures are made in order to improve the stress condition of the dam body,deal with the deformation of the dam body and strengthen the dam. |

| Keywords: | Core-wall earth dam Non-linear finite element Deformation Stress |
