混凝土面板堆石坝是近年来发展较快的坝型,上游防渗面板对大坝安全具有决定性作用,在面板混凝土中掺入聚丙烯纤维可有效提高面板质量。文章结合前期试验研究成果,对聚丙烯纤维混凝土的配合比、纤维掺量、施工技术进行研究,为聚丙烯纤维在面板堆石坝的应用提供指导,研究成果还特别对它在近年来新出现的溢流面板堆石坝坝顶溢洪道中的应用,提出合理性和可行性。
Concrete faced rockfill dam is developed rapidly in recent years, the dam, the upstream anti-seepage panel dam has a decisive role in the safety of concrete dipped in polypropylene fiber can effectively improve the panel quality. Combined with the results of previous experimental research, this paper studies the mix proportion, fiber content and construction technology of polypropylene fiber concrete, and provides guidance for the application of polypropylene fiber in concrete faced rockfill dam. The research results especially appearing in recent years The application of overflow face rockfill dam crest spillway, put forward the rationality and feasibility.
