One of the most popular modern methods of tunnel linings’ calculation with account for their interaction with the soil is finite element method. Because of the constant increase of computation capacities at the present time the tasks of algorithm development dominate, which account for the lining operation - soil for complicated geological conditions. The given work presents the computational algorithm of account of the distribution nonuniformity of the physical characteristics of ground medium over the surface of finishing at intersection of the interface of geological layers by the tunnel axis. The algorithm uses mathematical models of the finite elements method and it is adapted for the realization in the system of stress analysis of tunnel linings developed by the authors. The authors enumerate the disadvantages of different calculations and try to overcome them. For this aim the beam model of the system “lining - soil” is suggested.
