NUMERICAL ANALYSIS OF THE MAXIMUM EARTH PRESSURE ACTING ON TUNNEL LINING
The paper discusses the application of a new analytical method for the direct determination of the maximum earth pressure acting on a tunnel lining and the method follows similar techniques being employed in elastic analysis, although the medium around the tunnel is assumed to be viscoelastic. The time when the lining is installed after excavation is also considered in this proposed method. A brief description of the proposed method is given and the finite element analyses are presented for circular, elliptical, and horseshoe-shaped linings installed in the homogeneous and isotropic underground medium. Numerical results calculated by the finite element method are compared with the analytical solutions, these showing good agreement. The effects of shape and rigidity of the lining and the opening above the lining crown on the earth pressure are discussed.
