Abstract: The horizontal layer is the key part that affects the strength, stability and seepage of a RCC dam. For a RCC gravity dam with high seepage pressure during operation period, combined with the measured values of seepage pressure in dam body, the anti-sliding stability on dam layer is reviewed by use of material mechanics method and current industry standard Design Specification for Concrete Gravity Dams. The calculation results show that for the RCC dam with a small dam height, the seepage pressure on dam layer has little influence on the anti-sliding stability, and the redundancy of anti-sliding stability is high.

Key words: RCC dam, seepage pressure on layer, on-site inspection, anti-sliding stability
