Description
The Geneva Basin consists of a variety of geological formations, including Mesozoic limestone, Cenozoic Molasse, and Quaternary moraines. A 3D ground model has been developed using existing geological data; however, significant uncertainties remain in several areas along the proposed FCC tunnel alignment due to the limited extent of previous site investigations.
This poster summarises ongoing research aimed at evaluating the current geological understanding along the FCC trace and identifying the zones of greatest uncertainty. It also outlines the scope and objectives of the first subsurface site investigation campaign, currently underway, which is essential for informing both the exact elevation and tilt of the alignment as well as the detailed design of the tunnel.
