松树岭水电站混凝土坝温控问题的探讨

Research on Temperature Control of Concrete Dam of Songshuling Hydropower Station

根据大坝已浇混凝土的温度实测值,验算了基础温差值已控制在容许范围内,用工程类比的方法,提出了内外温差的控制标准值,对上、下层温差及相邻坝块高差、温度控制措施等提出了若干建议,供监理及施工单位参考。

According to the observed concrete temperature data of Songshuling gravity dam, it is shown that the temperature difference of dam foundation is controlled in permissible range. The control criterion for interior-border temperature difference of dam block is provided by engineering analogue. The temperature difference between upper layer and lower layer, the height difference between neighbouring blocks, and several temperature control measures are suggested.
