大坝贴坡技术在水库除险加固中的应用

On the Application of Dam Fitting-Slope Technology to Reservoir Reinforcement

广西上思县念伦水库内坡局部坍塌且受冲刷严重,根据经济、实用的原则,采用现浇混凝土板护坡的形式进行加固。文章以念伦水库除险加固工程为例,介绍大坝贴坡混凝土施工机械布置、施工程序、施工方法、质量控制措施,并探讨大坝内坡施工需要注意的问题。

Nianlun Reservoir in Shangsi County,Guangxi,has serious collapse and erosion problems in some parts of its dam slopes.Based on the economic and practical principles,it has been reinforced by cast-in-place concrete slabs.The paper sets forth ways to reinforce reservoir with an example of Nianlun Reservoir,introducing its machinery arrangement, construction procedures,construction methods and quality control for concrete construction,and exploring some issues to be aware of in the construction of dam slopes.
