PROBLEMS
6 The figure below represents a plan view of a vertical shaft, with a clay-filled
fault located near the shaft boundary. The state of stress at the particular horizon
is hydrostatic, of magnitude 8 MPa. The resistance to slip on the fault is purely
cohesive, and of magnitude 1.5 MPa.
Determine the maximum shear stress generated on the fault after development of
the shaft, and determine if the elastic stress distribution can be maintained.
