水布垭高面板堆石坝堆石体压实密度的研究

Study on Compactness of Rock Filler in High Concrete Faced Rockfill Dam of Shuibuya Project

水布垭砼面板堆石坝，坝高２３３ｍ，系当今世界同类坝型中最高的坝。面板堆石坝的设计以坝体和面板所产生的变形量为控制条件；堆石体高密实度和低孔隙率是减小坝体和面板变形的关键。通过水布垭面板堆石坝的现场填筑碾压试验，获得了合适的施工碾压参数，从而确保堆石体的高密实度。

The proposed Shuibuya concrete faced rockfill dam will be 233m high,which will be the highest in the world.The deformations generated by the dam and face plate are control conditions of design.The higher compactness and lower porosity in rockfill are the key to the deformations of the dam and face plate.By means of in situ reclamation and compaction tests of the Shuibuya Project,the proper parameters of compaction are found.The compactness of the rockfill thus can be ensured.
