Question

The maximum height of a gravity dam of elementary profile to be built by concrete of relative density = 2.4, on a foundation material of safe allowable stress = 7.5 MPa, by ignoring the uplift force is

• A. 319 m
• B. 484 m
• C. 125 m
• D. 225 m

Answer 1

The correct option is D 225 m

$H=\frac{f}{{\gamma }_w(G+1-C)}$

$=\frac{7.5\times {10}^3}{9.81(2.4+1-0)}$

$=224.86m$
