摘要
阿海水电站挡水建筑物为碾压混凝土重力坝,坝基渗流对工程安全的影响至关重要。结合坝基渗控分析,开展了坝体材料分区、筑坝材料性能、新材料应用等方面的研究,对大坝防渗系统进行了设计,采用了坝体二级配碾压混凝土、坝基防渗帷幕、坝锺设置黏土铺盖、上游坝面设防渗涂层等综合措施。防渗系统完成后,可有效地减少坝体～坝基系统的渗漏,降低坝基及坝内的扬压力,保证大坝的长期安全运行。
The water retaining structure of Ahai Hydropower Station is roller compacted concrete gravity dam. The foundation seepage is essential to the safety of project. Combining with the analysis of dam foundation seepage control, the material zoning of dam body, the properties of damming materials and the application of new materials are studied and the dam seepage control system is specially designed. The dam seepage is controlled by using two-graded RCC in dam body, arranging anti-seepage curtain in dam foundation, setting clay blanket on dam heels and painting impermeable coating on dam upstream surface. The seepage control system can effectively reduce the leakage of dam-foundation system and the uplifts within dam foundation and dam body to ensure the long-term safe operation of dam.
