摘要
广州抽水蓄能电站上库钢筋混凝土面板堆石坝仅用27个月建成,在国内首次成功地使用河滩砂砾料做垫层料,使用无轨滑模浇筑面板及三角区混凝土,优选混凝土原材料及配合比,严格控制混凝土塌落度和施工工艺,使面板混凝土裂缝少,质量优良。
It took only 27 months to build up the upper resrevoir CFRD. The river sand graver was successfully used for the bedding material and the facing concrete was placed by means of the slip form without the guide rail. The concrete was of the optimum proportioning ans its quality was under rigorous control so that very few fissures existed in the concrete facing.
