Abstract EN
The forecast of settlement and movements caused by tunneling represents a significant challenge of technology.
The evaluation of these movements is indeed of primary importance in order to prevent them.
The methods of calculation making it possible to evaluate displacements and deformations in the ground due to tunneling give only one approximation of the true amplitudes of the movements in the ground.
It is one of the assets of the Finite Element Method (FEM) which makes it possible a priori to treat configurations more complex and closer to reality.
Our objective in this study is to calculate numerically the various movements caused by the construction of a shallow tunnel using a shield using PLAXIS 2D, the behavior of the ground is described by a perfectly plastic elastic model based on the criterion of Mohr-Coulomb.
A comparison between the various methods : empirical, analytical and numerical in terms of settlement on the surface was carried out.
The validation of these results was made by using results drawn from literature.
We have also carried out a parametric study in order to analyze the influence of various geometrical and geotechnical parameters on the behavior of grounds due to tunneling.
Lastly, we have treated the same example by supposing the existence of structures near the tunnel in order to see the influence of the presence of other structures on the profile of the settlements caused by tunneling.
Results of our work agreed with those in literature.
