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
