Show a section of a gravity dam built of concrete examine the stability of this section at the base. The earth quake may be taken as equivalent to 0.1g for horizontal forces and 0.05g for vertical forces. The uplift may be taken as equal to the hydro-static pressure at the either ends and is considered 60% of area of the section. Assume unit weight of concrete = 24kn/m3 Unit weight of water = 10kn/m3
