Problem 3-108 The section of a concrete dam is shown in the figure. Concrete weights 23.5 kN per cubic meter and water weighs 9,790 N per cubic meter. Coefficient of friction between the dam and foundation is 0.55. Determine the factors safety against sliding and against overturning, and also the soil pressure at the heel and toe. Assume hydrostatic uplift varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe. Consider 1 m length of dam. Ans: FS0 = 2,20; FSs=1.66 Theel = 85.2 kPa; qwe = 300.2 kPa

The section of a concrete dam is shown in the figure. Concrete weights 23.5
KN per cubic meter and water weighs 9,790 N per cubic meter. Coefficient of
friction between the dam and foundation is 0.55. Determine the factors of
safety against sliding and against overturning, and also the soil pressure at the
heel and toe. Assume hydrostatic uplift varies uniformly from full hydrostatic
head at the heel of the dam to zero at the toe. Consider 1 m length of dam.
Ans: FS0 = 2,20; FSs=1.66
Theel = 85.2 kPa; qe = 300.2 kPa
