Question
Download Solution PDFFor concrete gravity dams (having strength of 3000 kN/m2), the limiting value of the height for low gravity dam is approximately: (G(concrete) = 2.4)
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Possible height for concrete gravity dams are given as;
\(H={f\over\gamma_w(G_c+1)}\)
Where f = allowable stress or strength, Gc = specific gravity of concrete, and \(\gamma_w\) = unit weight of water.
Calculation:
Given; f = 3000 kN/m2, Gc = 2.4
\(H={3000\over10\times (2.4+1)}=88.235\approx 88\, m\)
Hence option (3) is the correct answer.
