中国混凝土面板堆石坝的技术进步

Technical advances in concrete face rockfill dams in China

  • 摘要: 首先阐述了中国20余年来混凝土面板堆石坝的发展概况,简要说明了已建和在建的94座坝高100 m以上的高混凝土面板堆石坝的主要技术特征和自主创新,包括上下游坝坡、面板厚度、宽度和配筋率、趾板宽度、坝体分区、筑坝材料、填筑标准、接缝止水和工程用途。展示了中国在国际混凝土面板堆石坝工程领域的领先地位。接着阐述中国混凝土面板堆石坝筑坝技术所取得的进展,分别阐述了设计技术、施工和监测技术、筑坝材料(软岩和砂砾石)和防渗结构(面板和止水)关键技术,不利自然条件下(狭窄河谷、高陡岸坡、深覆盖层、地震区和高寒区)的筑坝关键技术以及计算和试验研究等方面的技术进步和创新,最后简述了未来超高面板堆石坝的挑战和展望。

     

    Abstract: The development of concrete face rockfll dams (CFRD) in China for more than 20 years is introduced. The main features including dam slope, thickness, width and reinforcement ratio of face slab, width of plinth, dam zoning, type of rockfill and function of project and some initiative creations about design concept, placement criteria and water-stop are presented. China's leading position in the worldwide CFRDs is shown. The technical advances and creations in the design, construction, test, research, inspection, safety monitoring of CFRDs are described. The construction technology using soft rock and sand gravel as embankment materials as well as the key technology for building CFRDs at the site with bad natural features including narrow river valley, steep river slope, deep overburden layer, strong earthquake zone and severe cold zone is also presented. The challenge and prospect for supper-high CFRDs in the future are proposed.
