A circular concrete shaft liner with a Youngs modulus of 23.45GPa, Poissons ratio of 0.25, unconfined compressive
Question:
A circular concrete shaft liner with a Young’s modulus of 23.45GPa, Poisson’s ratio of 0.25, unconfined compressive strength 24.1 MPa, and tensile strength 2.41 MPa is considered for control of water pressure (1.31 MPa) at a depth of 1,143 m. Inside shaft diameter after lining must be 5.5 m. Find the liner thickness necessary to achieve a safety factor of 2.5. What outside shaft diameter is indicated?
