Design Research and Practice on Impervious Materials for the Core Wall of Nuozhadu Rockfill Dam

摘要：

　　The maximum height of the core-wall rockfill dam of Nuozhadu Hydropower Station is 261.5 m.The impervious materials of the core wall are composed of natural earth mixed with artificially graded crushed stones, namely earth mixing gravel.To solve the technical difficulties associated with the impervious materials for the super high rockfi1l dam, comprehensive researches were carried out, including survey and characteristic tests of the natural earth, in situ tests of construction techniques, filling and compaction quality control, safety monitoring and feedback analysis and so on.The research and design achievements in the above aspects are introduced.
