A 6 m diameter circular shaft is planned in massive rock. Laboratory tests on core from exploration

Question:

A 6 m diameter circular shaft is planned in massive rock. Laboratory tests on core from exploration drilling show that

Co = 152 MPa To = 8.3MPa

γ = 23kN/m3 E = 34.5GPa

G = 13.8GPa

Depth is 915 m. Site measurements show that no tectonic stresses are present. Determine the factors of safety with respect to failure in compression and tension.
