| 中文摘要: |
| 混凝土大坝加高加厚后，坝体的应力状况是一个很重要的问题。本文结合英那河大坝加高工程，用有限元方法对混凝土大坝设槽以改善大坝应力方案进行了优选研究，给出了最佳的设槽方案和设槽位置，并仿真分析了坝体的应力状况。研究结果证实，设槽可以明显地减小坝体应力。 |
| 英文摘要: |
| The effect of grooves on improving the stress state of heightened concrete dam is demonstrated by means of FEM. On this basis, the optimal setting of grooves for Yingnahe Dam is further investigated. The simulation calculation for the whole construction process of the heightening shows that the stress distribution of the dam is remarkably improved when two grooves are adopted. |
