摘要
真宝顶水库海拔较高,所处理地理位置气温低而寒冷,昼夜温差大,对坝面混凝土防冻防裂极为不利。为此,通过优选混凝土原材料,改进施工工艺,裂缝控制,科学养护等措施,提高了混凝土质量,有效地防止了混凝土的冻害、裂缝产生,取得了良好的效果。
Zhenbaoding reservoir falls in a location characterized by high elevation, low temperature, great difference in temperature of day and night, which disfavors the frost and crack protection of dam surface concrete. In order to improve the quality of concrete and effectively protect concrete from frost or crack damage, a series of measures were taken such as selecting optimum concrete raw materials, improving construction technology, controlling crack, scientific curing etc., yielding satisfactory effect.
