STRESSED STATE OF THE LINING OF A CIRCULAR TUNNEL PARTIALLY FILLED WITH WATER

The determination of the stressed state of the lining of a partially filled tunnel (the level of water in the tunnel is below the crown of the lining roof) involves the solution of the 2 dimensional problem of elasticity on the equilibrium of a ring in an elastic medium loaded by normal stresses. Such a solution may be used to calculate the load on the lining in the case of a varying water level in the tunnel, i.e. during emptying or filling. This type of calculation is most expedient for tunnels in weak locks with low modilii of deformation. An algorithm is presented which is derived by expansion of the acting load in a Fourier series and subsequent examination of the appropriate boundary-value problem of the theory of analytic functions. The proposed algorithm can be used to determine the stressed state in a circular tunnel lining under the action of other types of static loads symmetric to the vertical axis and distributed in any manner on a part of the inside contour of the lining cross section.
