| Abstract: | Under the operating conditions of low temperature and high water level, the dam of Baishan hydropower station appears enlargement problem of deformation and leakage. Based on the observed data of typical dam section, the dam running behavior is analyzed. The results show that the dam running at the conditions of low temperature and high water level is the main reason for increasing the deformation and water leakage. Therefore, it suggests strengthening monitoring and ensuring dam safety operation. |
