十三陵蓄能电站上水库面板质量检测和抗冻性评估

十三陵抽水蓄能电站上水库的钢筋混凝土面板是一种在严酷冻融循环条件下运行的钢筋混凝土结构。为保证电站安全稳定运行，进行了上水库面板混凝土强度和缺陷的跟踪检测，建立了面板混凝土温度和冻融循环微机自动检测系统，开展了不同配合比在板混凝土模拟试件的抗冰试验及面板混凝土室内外对比关系的试验研究，并对面板混凝土的抗冻安全性作了初步评估，上述工作取得了初步成果，为上水库的安全持久运行奠定了良好的基础。

Quality check and anti-freeze evaluation on the face slab for the upper reservoir of Shisanling Pumped Storage Power Station

The reinforced concrete face slab for the upper reservoir of the Shisanling Pumped Storage Power Station is a structure under bitter cycle of freezing and thawing. To ensure the safety and stable operation of the power station, the track check on the strength and defect of the reinforced concrete face slab for the upper reservoir was conducted. The automatic check computer system for the temperature and the cycle of freezing and thawing of reinforced concrete face slab was set up. The anti freeze test of concrete face slab at deferent mix proportion was made and the test and study on the relationship of concrete face slab between outdoor and indoor were also made. The preliminary evaluation on the anti freeze safety of the concrete face slab was conducted. Some preliminary results were gained, which lays a good foundation for the safe and long term operation of the upper reservoir.
