3. 777 Y
Considering the unit length of the dam, when the water level rises to the dam crest level (the highest level) in the dam, the section of which is given in the figure;
a-) By accepting the base as impermeable; Determine the weights of regions 1,2 and 3 of the dam, the horizontal and vertical components of the pressure forces acting on the dam, and find the perpendicular distances of the action points of these forces to the O point. (X=3 m, Y=3 m, Z=8 m, H=22 m and γdam=2.4 t/m3 shall be taken.)
b-) By accepting the base as impermeable; Determine the safety factor against overturning.
c-) By assuming that the bottom is permeable and the pressure distribution of the groundwater linear; Determine the ground water pressure force due to the ground water and the vertical distance of the effect point of this force to the O point.
d-) By accepting the base as permeable; Determine the safety factor against overturning.
