摘　　要：针对湖北水布垭230m级高面板堆石坝工程,研究了宽级配垫层料的级配范围及其防渗,抗渗稳定性,反滤性,压实性及压实标准。提出了合理的垫层料级配范围和压实控制干密度,论证了建议级配范围内的垫层料有较高的抗渗稳定性。Based on the Shuibuya concrete-faced rockfill dam 230m in height the paper has made a study of grading limits of its wide grading cushion materials and of their impermeability, seepage-resisting stability, filtering, compactness and compacting standard, put forward the rational grading limits and compacted control dry density of the cushion materials and proved the high seepage-resisting stability within the proposed grading limits of the cushion materials.
