| 摘 要： | 洞坪水电站原拟定在大坝391.0 m高程设置两个6 m×8 m导流底孔参与渡汛.后来施工布置、施工进度、大坝体型和泄洪建筑物等均进行了优化调整,为重新研究导流渡汛方案提供了前提条件.结合大坝可能的施工进度形象、渡汛设计标准和洪水机遇分析、坝体稳定、应力条件及可能的经济、技术措施等方面的深入研究,提出了取消导流底孔和确保施工期最为关键的2004年安全渡汛措施.实践证明取消导流底孔不仅节省了工程投资、方便了施工,而且缩短了工期.

| Abstract: | In the preliminary plan two 6 X 8 m bottom outlets are placed on elevation 391 of dam body. Afterwards, the structure of dam and construction planning are readjusted, through the analysis on flood probability, dam stability and economic-technical feasibility, it is observed that to concel the bottom outlet is possible and has been sucessfully implemented in practice. |
