抽水蓄能电站沥青混凝土防渗护面的技术综述

结合国内抽水蓄能电站的实际情况,介绍了水工沥青混凝土防渗结构的技术特点、配合比设计、施工技术及质量控制情况,论证了水工沥青混凝土技术是成熟的、可靠的。沥青混凝土面板与钢筋混凝土面板防渗的综合造价分析对比表明二者造价相当。根据技术和造价分析,建议在抽水蓄能电站水库防渗中推广使用水工沥青混凝土。

Summary of Asphalt Concrete Anti-seepage Facing Technology in Pumped Storage Power Station

Hydraulic asphalt concrete has many advantages in anti-seepage aspects,especially suitable for reservoir's anti-seepage facing in pumped storage power station.The development and application of this technology is not sufficient in recent years mainly own to worrying about its reliability and its high cost.In this paper,the technical characteristics,mixture design,construction equipment,construction technology and quality control is introduced by considering the actual situation in Baoquan Pumped Storage Power Station.All of these demonstrate clearly that the technology of hydraulic asphalt concrete is mature and reliable.Furthermore,cost comparison between asphalt concrete facing and cement concrete facing shows that the costs in both anti-seepage types are in narrow margin.According to the analysis in technical and cost aspects,it is strongly recommended to adopt asphalt concrete facing in pumped storage power station.
