Problem 2: A concrete dam retaining water is shown in the figure below. Consider the hydrostatic uplift pressure that varies uniformly from 80% at the heel to 25% at the toe. Using the following data: b= 3m, B=15m, a=3m, c=2m, d-1.80m, and the slope of the inclined portion at the upstream face is 1.20H:1.80V while that of the downstream portion is 2.25H:4V. Using 24 kN/m' for the concrete, determine the a. Maximum depth of water such that the total vertical reaction falls within the middle thirds. Consider 0.50m interval for the line of action of the total vertical reaction. b. Overturning moment c. Resisting moment d. Factor of safety against overturning e. Min. coef. of friction between the dam and soil f. Foundation pressure at the heel g. Foundation pressure at the toe Figure: B
