| 为研究渗流作用下尾矿坝变形规律，本文以西藏地区某高寒高海拔地区尾矿库坝体为研究对象，通过分析降水和无降水两种工况下坝体变化情况，研究渗流作用对坝体稳定性的影响。研究结果表明：降水对坝体渗流作用具有显著影响，这种增强的渗流作用直接影响了坝体的稳定性。通过研究渗流作用下的坝体变形规律，可以为尾矿库的设计和改进提供重要参考，进一步提高其抗渗性能和抗震性能，确保其长期安全运行。因此，这项研究成果不仅对于解决西藏地区高寒高海拔环境下尾矿库安全稳定性问题具有重要意义，也为类似环境下水工建筑的安全管理提供了有益启示。 |
| 英文摘要: |
| In order to study the deformation law of tailings dam under seepage action， the dam body of tailings dam in a cold and high altitude area in Xizang is taken as the research object， and the influence of seepage action on the stability of dam body is studied by analyzing the changes of dam body under the conditions of precipitation and no precipitation. The research results indicate that precipitation has a significant impact on the seepage effect of the dam body， and this enhanced seepage effect directly affects the stability of the dam body. By studying the deformation law of the dam body under seepage， important references can be provided for the design and improvement of tailings ponds， further improving their impermeability and seismic performance， and ensuring their long-term safe operation. Therefore， this research achievement is not only of great significance for solving the safety and stability problems of tailings ponds in the cold and high altitude environment in Xizang， but also provides beneficial enlightenment for the safety management of hydraulic structures in similar environments. |
