The procedure is bs~ed on the solution of the plane contact problem of elasticity theory of a noncirculsr ring with one axis of symmetry in an elastic medium with the principal axes of t h e ordinary stresses arbitrarily inclined to the vertical and horizontal. 77~o79 TALE OF A TUNNEL OR THE SURVIVAL STORY OF S'JB.
