A triangular concrete dam shown having a face height of $20m$ and a base of $B=16m.$ The depth of water on one side of the dam is $20m.$ The coefficient of friction between the dam and the foundation is $0\mathrm{.}70.$ Assume impervious foundation $($no seepage in the base foundation$).$ The density of concrete is $2400k\frac{g}{m^3}.$

$($a$)$ Consider one$-$meter strip of dam, compute for the total hydrostatic pressure acting on the wall of the dam.

$($b$)$ Compute for the factor of safety against sliding.

$($c$)$ Compute for the factor of safety against overturning.

Ans.

$($a$)F=1962kN$

$($b$)F{S}_S=1\mathrm{.}344$

$($c$)F{S}_o=3\mathrm{.}072$
