Abstract: Nuozadu high core wall rock-fill dam is 261.5 meters high, the highest at home and the third in rank worldwide. The dam locates in southwest China, where the earthquakes are frequent and strong, and so the anti-seismic safety of the dam is of vital importance. There are few experiences for reference domestic and overseas. Therefore, plenty of research on key technical issues of anti-seismic safety were carried out and applied in project. In this paper, research results and the final design programs on anti-seismic safety of Nuozadu high core wall rock-fill dam are introduced, which can provide references for anti-seismic safety design and research of similar projects.

Key words: Nuozadu high core wall rock-fill dam, anti-seismic safety, seismic wave, liquefaction, anti-seismic measures

摘要： 糯扎渡高心墙堆石坝最大坝高261.5 m， 在当前同类坝型中居世界第三、 国内第一， 坝址位于我国西南强震区， 区域地质条件复杂， 地震频繁、 强度大， 因此大坝的抗震安全至关重要。国内外可借鉴的经验较少， 因此对大坝抗震安全相关的关键技术问题开展了大量的深入研究， 并应用到工程实际中。本文介绍了糯扎渡高心墙堆石坝抗震安全相关的课题研究成果及最终的抗震设计方案， 为同类工程的抗震设计及研究工作提供了参考。
