For the stability analysis of a gravity dam, the forces that always ACT (not conditional) include:
Choose the correct answer
Wind load and earthquake load
Self weight of dam, water pressure on upstream face, and uplift pressure
Wave pressure only
Only earthquake force
Correct Answer
B. Self weight of dam, water pressure on upstream face, and uplift pressure

Gravity dam stability forces: self-weight (W), hydrostatic water pressure (horizontal and vertical components), silt pressure, uplift pressure (from seepage through foundation). Wind, wave, and earthquake loads are occasional/conditional loads superimposed on normal loads.
