A cross-section of a concrete gravity dam is shown in figure. Analyze the stability of block A for empty and full upstream reservoir cases, separately. Ignore earthquake, silt wave and ice forces. Specific weights of concrete and water are 23kN/m3 and 10kN/m3, respectively. Compressive and shear strengths of concrete are 35MPa and 6MPa, respectively. The coefficient of friction between concrete blocks is 0.65. There is no tail water in downstream. Safety factors will be ≥2 for overturning, will be ≥1.5 for sliding and will be ≥3 for shearsliding.

Ignore earthquake, silt wave and ice forces. Specific weights of concrete and water are 23kN/m' and 10kN/m', respectively. Compressive and shear strengths of concrete are 35MPA and 6MPA, respectively. The coefficient of friction between concrete blocks is 0.65. There is no tail water in downstream. Safety factors will be 22 for overturning, will be 21.5 for sliding and will be 23 for shear- sliding. 2.5m IH:3V 14m 1H:25V A 2H:3V 7m B
