Question
A concrete dam holds of static water as shown in the figure (not drawn to the scale). The uplift is assumed to vary linearly from full hydrostatic head at the heel, to zero at the toe of dam. The coefficient of friction between the dam and foundation soil is . Specific weights of concrete and water are and , respectively.
For NO sliding condition, the required minimum base width (in m, round off to two decimal places) is ________.

Correct answer
15 to 16
Solution
1.Horizontal water pressure force ():
2.Weight of the dam ():
3.Total uplift force ():
4.No sliding condition:
Rounding to two decimal places, the minimum base width is .Continue learning with Success Tracker
