| Summary: | The work presented includes a finite element method (hereinafter FEM) to estimate the elastic settlement produced by the excavation of a tunnel in a porous granular medium on a supposed perfectly impermeable stratum. In turn, on the impermeable layer, the porous medium is divided into two layers with different degrees of saturation. In contact with the upper layer there are buildings providing a joint surface load of 0.10 MPa. At a certain depth and at a certain horizontal distance from the foundation, the excavation of the tunnel of 10 meters in diameter is projected. A 2D FEM is modelled using the GMSH and MATLAB® tools. The displacements occurred in the terrain between the initial and the final state are calculated. Terzaghi's principle has been implemented in the MEF for the calculation of settlements |
