An underground storage cavern is solution mined in a thick salt bed where Co = 91.0 MPa

Question:

An underground storage cavern is solution mined in a thick salt bed where

Co = 91.0 MPa To = 8.5MPa

γ = 22.8kN/m3 E = 34.5GPa

G = 13.8GPa

and depth to the cavern center is 442 m. The cavern has a spherical shape and is 49 m in diameter. The premining stress is hydrostatic. Estimate the wall safety factor.
