摘要
拉西瓦水电站大坝为250 m高的双曲薄拱坝,自然条件恶劣,混凝土温控是影响大坝质量和安全的关键之一。通过对混凝土原材料的优选,制定了合理的夏季、冬季温控措施,并在施工中取得了良好的效果。拉西瓦拱坝混凝土冬季采用综合蓄热法施工,既保证了质量,加快了施工进度,又节省了投资。拉西瓦水电站的实践,为高寒缺氧地区高拱坝混凝土温控积累了经验。
The dam for Laxiwa Hydropower Station is a double curvature arch dam with the height of 250m and is located in an area with poor natural conditions, so that concrete temperature control is one of key measures affecting the quality and safety of the Dam. On the basis of the optimal selection of raw materials of concrete, we formulated rational temperature control measures in summer and winter, which had gained good effectiveness. The concrete construction of Laxiwa arch dam in winter adopted comprehensive heat storage method, which not only ensured its quality but also quickened the construction progress and saved investment. The practice of Laxiwa Hydropower Station provides experience for the concrete temperature control of high arch dam in cold and oxygen-shortage area.
