泽城西安水电站面板堆石坝混凝土配合比参数设计

Design of concrete mix proportion parameters of concrete faced rockfill dam in Zecheng Xi'an Hydropower Station

面板混凝土作为面板堆石坝工程防渗防裂设计的主要内容,其质量的好坏,直接影响大坝的整体防渗及安全运行。泽城西安水电站工程,根据面板堆石坝混凝土技术要求,通过逐段逐期的混凝土试配试验及细部论证,提出了面板混凝土最优配比,并经现场测试后,总结出面板混凝土施工时的注意事项。后期运用证明,该配比保证了面板混凝土的浇筑质量和防裂效果。

The quality of slab concrete,as the main content in the anti-seepage and anti-crack design of concrete faced rockfill dam project,directly affects overall anti-seepage and safe operation of the dam. The best mix proportion of slab concrete is proposed in Zecheng Xi ＇an Hydropower Station Project according to concrete faced rockfill dam concrete technical requirements through concrete fitting experiment and detail demonstration by sections and stages. The mix proportion is tested in the construction site. Precautions during construction of concrete faced rockfill dam are summarized.Subsequent operation proves that the mix proportion guarantees the pouring quality and anti-crack effect of slab concrete.
