| 英文摘要: |
| The experience of engineering practice, numerical analysis and model test shows that the occurrence of cracking in arch dam heel, especially for high arch dams, is hard to predict, because this location is under strong constraint during construction and its stress is very complicated after the dams put into operation. The cracks may further expand due to the hydraulic split action of high water pressure. To solve this problem, a new idea of using flexible water tight system to prevent the high water pressure entering the cracks is suggested. A conceptual model test is carried out to verify the feasibility of this new measure. The water head of the model test is as high as 300m. The test result shows that the water tight system is reliable and the material suggested by the authors can be used in engineering practice. |
