Tunnels

CESAR-LCPC has been used in many important tunnel projects (Groene Hart tunnel, Subway of Cairo, Channel tunnel...).

It is renowned for its capabilities to model projects from simple geometries (plane strain or axisymmetric analysis) to complex 3D intersections with applications of tunnelling methods (cut-and-cover, TBM, NATM...).

CESAR offers a wide and detailed set of features for modelling various aspects of tunnel engineering: construction process, lining setup, long-term effects, hydraulic loads, thermal loads...

The convergence-confinement method is proposed in a parametric and didactic way through a specific tool in C-TUNNEL, software dedicated for "draft" projects of tunnels.
