摘　　要：糯扎渡水电站心墙堆石坝最大坝高261.5 m,心墙防渗料采用天然土料掺入人工级配碎石的掺砾土料。为解决超高心墙堆石坝防渗料的技术难题,在糯扎渡工程设计与实践中针对土料进行了料源勘察、土料特性试验、现场工艺试验、填筑压实质量控制以及安全监测与反馈分析等方面的综合研究,简要介绍了以上几方面所取得的科研设计成果。The maximum height of the core-wall rockfill dam of Nuozhadu Hydropower Station is 261.5 m.The core-wall impervious materials are composed of natural clay mixed with artificially graded crushed stones,namely gravel clay.For solving the technical difficulties associated with the impervious materials for the super high rockfill dam,comprehensive researches are carried out,including survey and characteristic tests of natural soils,in-situ tests of construction techniques,filling and compaction quality control,safety monitoring and feedback analysis.The research and design achievements in the above aspects are introduced.
