Sliding failure occurs in a solid gravity dam when____________________?
Correct answer: D. Shear friction factor Is less than 1.5
- A. Resultant of all forces cuts the base of the dam out side the toe
- B. Resultant of all forces cuts the base at the inner middle third point
- C. Ratio of over turning moments exceeds than unity
- D. Shear friction factor Is less than 1.5
Explanation
Sliding becomes unsafe when the factor of safety against sliding falls below the prescribed value, commonly 1.5 for a gravity dam. The other options describe overturning or eccentricity conditions rather than sliding failure.
