Question:
A 20 foot diameter circular shaft is planned in a massive rock. Laboratory tests on core from exploration drilling show that
Co = 22,000 psi To = 1,200 psi
γ = 144pcf E = 5 × 106 psi
G = 2.0 × 106 psi
Depth is 3,000 ft. Site measurements show that no tectonic stresses are present. Determine the factors of safety with respect to failure in compression and tension.
