The main program for calculating bored, excavated, and backfilled or plugged tunnels is the MKE program, which allows for the solution of any geotechnical problem using the finite element method. The program includes a multitude of linear and nonlinear material models, an advanced finite element mesh generator, and options for easy modeling of beam and contact elements. Tunnel linings can be made of beam or plate elements.
The additional module MKE Tunnel provides specialized options for modeling tunnels using the sequential excavation method (SEM, NATM), such as the gradual increase in the strength of the main lining due to material aging or the gradual reduction of surrounding mass interaction (lambda method).
The impact of earthquakes on underground structures can be determined within a fully dynamic calculation in the additional module MKE Earthquake. The impact of excavations on surrounding structures can be determined using an analytical method in the Underground Losses program. In addition to the depression shape, the predicted failure of the upper structure due to uneven settlement can be calculated.
