Abstract: The sulfate distribution law and erosion type at Daxia hydropower station are given in this paper. By detecting and analyzing the drill core sampling, it is explained that the foundation treatment is in line with design requirements, the foundation concrete is of high compactness, impermeability and strength, and not subjected to sulfate attack.

Key words: foundation concrete, sulfate attack, analysis

摘要: 对大峡水电站硫酸盐分布规律及侵蚀类型进行了全面分析,通过钻芯取样检测分析,说明坝基处理符合设计要求,建基面混凝土密实性较好、抗渗较好、强度较高,未受到硫酸盐侵蚀。
