Question
A section of a gravity masonry dam is shown in the figure water is flush at the top of the dam
upstream and 5m from the ground downstream. Assume hydrostatic uplift to vary uniformly
from full hydrostatic pressure from the heel to zero at the drain density of water is 1000kg/m^3.
The specific gravity of concrete is 2.4. Determine:
a. The location of the resultant force
b. Factor of safety against sliding if coefficient of friction is 0.75
c. Factor of safety against overturning
d. Stress at the heel and the toe
e. Unit horizontal shearing stress at the base
f. Factor of safety against overturning neglecting uplift
